Dynamic transcriptional variations of genes encoding fructan active enzymes (FAZYs; 1-SST, 1-FFT, 1-FEHI, 1-FEHII) alongside their potential contributions regarding production/degradation of various carbohydrates (i.e., fructose, glucose, sucrose, 1-kestose, and inulin) were scrutinized in the two distinct genotypes of chicory (Cichorium intybus L.) namely “Germany variety” and “Iranian landrace”, at flowering stage. Germany variety accumulated overall more amounts of fructose, sucrose, and inulin, while Iranian landrace contained the highest proportion of 1-kestose, and glucose. Instead, in both genotypes, maximum transcript levels of 1-FEHI were detected in stem, while root, flower and leaf tissues possessed inferior magnitudes. Considering 1-FEHII, both genotypes exhibited a down-regulated behavior in four tissues (excluding landrace stem). Regarding landrace, both 1-SST and 1-FFT correlated only with glucose, while for Germany variety, 1-SST had a strong association with inulin, 1-ketose, alongside glucose, and 1-FFT had a strong correlation only with glucose. Notably, 1-FEHII neg. correlated with inulin content, indicating an “antagonistic” effect between inulin accumulation/production and 1-FEHII activity. The results, overall, demonstrated that variations in genotypes and/or tissues under study can synergistically/antagonistically influence expression patterns of FAZY genes alongside production/degradation of the corresponding fructans. In the experiment, the researchers used many compounds, for example, (2R,3R,4S,5S,6R)-2-(((2S,3S,4S,5R)-2-((((2R,3S,4S,5R)-3,4-Dihydroxy-2,5-bis(hydroxymethyl)tetrahydrofuran-2-yl)oxy)methyl)-3,4-dihydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)oxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol (cas: 470-69-9Related Products of 470-69-9).

Tetrahydrofurans and furans are important oxygen-containing heterocycles that often exhibit interesting properties for biological applications or applications in the cosmetic industry. Tetrahydrofuran can also be produced, or synthesised, via catalytic hydrogenation of furan. This process involves converting certain sugars into THF by digesting to furfural. An alternative to this method is the catalytic hydrogenation of furan with a nickel catalyst.Related Products of 470-69-9

In this study we evaluated the proximate composition of two Solanaceae fruits from Brazilian Cerrado, their mineral content, volatile organic compounds (VOCs), phenolic compounds profile, and antioxidant capacity employing Oxygen Radical Absorbance Capacity (ORAC) assay, for each part of the fruits (pulp, peel and seeds). Our results showed that the pulp has a high moisture content (74.62-85.40 g/100 g) and soluble fiber (1.29-2.06 g/100 g) content, and low fat, protein, and ash content. The peel exhibited high levels of carbohydrates and total fibers (6.55-11.39 and 12.35-13.12 g/100 g, resp.), while the seed presented high content of fat, protein, and insoluble fiber (10.14-12.62, 9.14-13.24 and 19.84-23.15 g/100 g). Potassium is the main mineral found in both fruits. It is the first time that the carbohydrate profile, volatile components, and phenolic compounds of the fruta-do-lobo and jua-acu are reported. 1-Kestose (GF2) and nystose (GF3) were found in both fruits. The main VOCs of jua-acu were esters, while in fruta-do-lobo, aldehydes were the major components. UPLC-Q-ToF fraction anal. of jua-acu and fruta-do-lobo revealed 24 phenolic compounds, most being hydroxycinnamic acids derivatives in jua-acu, and chlorogenic acids in fruta-do-lobo. The antioxidant capacity (ORAC) of the fruits ranged from 1.35 to 11.51 μmol TE/100 mL of extract These results indicate that Solanum genus can be interesting for the Brazilian fruit market, and that it has potential to be exploited for agroindustry for diversification of fruit products. In the experiment, the researchers used many compounds, for example, (2R,3R,4S,5S,6R)-2-(((2S,3S,4S,5R)-2-((((2R,3S,4S,5R)-3,4-Dihydroxy-2,5-bis(hydroxymethyl)tetrahydrofuran-2-yl)oxy)methyl)-3,4-dihydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)oxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol (cas: 470-69-9Synthetic Route of C18H32O16).

Fructooligosaccharides (FOSs)-fructose-based oligosaccharides-are typical prebiotics with health-promoting effects in humans and animals. The trisaccharide 1-kestotriose is the most attractive inulin-type FOS. We previously reported a recombinant sucrose:sucrose 1-fructosyltransferase (1-SST, EC 2.4.1.99) from Schedonorus arundinaceus (Sa) that efficiently converts sucrose into 1-kestotriose. In this study, Pichia pastoris PGFT6x-308 constitutively expressing nine copies of the Sa1-SST gene displayed fructosyl-transferase activity in undisrupted biomass (49.8 U/mL) and culture supernatant (120.7 U/mL) in fed-batch fermentation (72 h) with sugarcane molasses. Toluene permeabilization increased 2.3-fold the Sa1-SSTrec activity of whole cells entrapped in calcium-alginate beads. The reaction with refined or raw sugar (600 g/l) yielded 1-kestotriose and 1,1-kestotetraose in a ratio of 8:2 with their sum representing above 55% (wt/wt) of total carbohydrates. The FOSs yield decreased to 45% (wt/wt) when sugarcane syrup and molasses were used as cheaper sucrose sources. The beads retained 80% residual Sa1-SSTrec activity after a 30-day batchwise operation with refined cane sugar at 30°C and pH 5.5. The immobilized biocatalyst is attractive for the continuous production of short-chain FOSs, most particularly 1-kestotriose. In the experiment, the researchers used many compounds, for example, (2R,3R,4S,5S,6R)-2-(((2S,3S,4S,5R)-2-((((2R,3S,4S,5R)-3,4-Dihydroxy-2,5-bis(hydroxymethyl)tetrahydrofuran-2-yl)oxy)methyl)-3,4-dihydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)oxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol (cas: 470-69-9Related Products of 470-69-9).

THF can also be synthesized by catalytic hydrogenation of furan. This allows certain sugars to be converted to THF via acid-catalyzed digestion to furfural and decarbonylation to furan, although this method is not widely practiced. THF is thus derivable from renewable resources.Related Products of 470-69-9

Comparison of antigenicity and conformational changes to β-lactoglobulin following kestose glycation reaction with and without dynamic high-pressure microfluidization treatment was written by Zhong, Junzhen;Yu, Hongda;Tu, Yue;Zhou, Lei;Liu, Wei;Luo, Shunjing;Liu, Chengmei;Prakash, Sangeeta. And the article was included in Food Chemistry in 2019.Related Products of 470-69-9 This article mentions the following:

Previous work indicated that conformational changes of β-lactoglobulin (β-LG) induced by dynamic high pressure microfluidization (DHPM) was related to the increase of antigenicity. In this study, β-LG glycated with 1-kestose and combined with DHPM decreased the antigenicity of β-LG. The antigenicity of control, β-LG-kestose (0.1 MPa) and β-LG-kestose (80 MPa) were 100, 79 and 42 μg/mL resp. The mol. weight of β-LG conjugated to kestose increased from 18.4 to 19.6 kDa and its conformation scarcely changed. Conversely, combined with DHPM treatment (80 MPa), β-LG conjugated to kestose formed two conjugates with mol. weight of 18.8 and 19.8 kDa, resp. Furthermore, the unfolding of β-LG as a result of the treatments is reflected by a decrease of intrinsic and synchronous fluorescence intensity and changes to the secondary structure. The conformational changes induced by DHPM and glycation treatments synergistically decrease the antigenicity of β-LG due to more masked or disrupted epitopes.

Improvement of 1-Kestose-producing enzyme was written by Fujii, Tadashi;Tochio, Takumi. And the article was included in Oyo Toshitsu Kagaku in 2021.Related Products of 470-69-9 This article mentions the following:

Fructooligosaccharide (FOS) is a polymer in which β-2, 1-linked fructose units are transferred to sucrose and is widely used as a prebiotic. In particular, it has been reported that kestose, which is a trisaccharide FOS, has a particularly high prebiotic function, such as the selective growth of useful intestinal bacteria such as fatty acid-producing bacteria. In order to efficiently produce kestose, the author attempted to obtain an enzyme that specifically produces kestose by suppressing the byproduct of kestose, which is the FOS of tetrasaccharides. As a result of screening using the Escherichia coli surface presentation method, BiBftA H395R / F473Y, a variant of the enzyme derived from Beijerinckia Indica, specifically accumulated kestose. In particular, H395R is an important mutation, and it is considered that it suppresses the formation of long chains longer than kestose and also suppresses the degradation of sucrose without transglycosylation. As a result of confirming the time course of the reaction, about 44% of sucrose was converted to kestose by BiBftA H395R / H473Y, and at this time, the byproduct of sucrose was suppressed to about 1%. This improved enzyme was thought to contribute to the dramatic reduction in production cost and improvement in production efficiency of kestose crystals. In the experiment, the researchers used many compounds, for example, (2R,3R,4S,5S,6R)-2-(((2S,3S,4S,5R)-2-((((2R,3S,4S,5R)-3,4-Dihydroxy-2,5-bis(hydroxymethyl)tetrahydrofuran-2-yl)oxy)methyl)-3,4-dihydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)oxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol (cas: 470-69-9Related Products of 470-69-9).

A great demand for prebiotics is driving the search for new sources of fructo-oligosaccharides (FOS) producers and for FOS with differentiated functionalities. In the present work, FOS production by a new isolated strain of Aspergillus ibericus was evaluated. The temperature of fermentation and initial pH were optimized in shaken flask to yield a maximal FOS production, through a central composite exptl. design. FOS were produced in a one-step bioprocess using the whole cells of the microorganism. The model (R² = 0.918) predicted a yield of 0.56, exptl. 0.53 ± 0.03 g_FOS.g^-1_{initial sucrose} was obtained (37.0°C and a pH of 6.2). A yield of 0.64 ± 0.02 g_FOS.g^-1_{initial sucrose} was obtained in the bioreactor, at 38 h, with a content of 118 ± 4 g. L^-1 in FOS and a purity of 56 ± 3%. The chem. structure of the FOS produced by A. ibericus was determined by HPLC and NMR. FOS were identified as 1-kestose, nystose, and 1^F-fructofuranosylnystose.

In traditional use, Panax medicinal plants (ginseng, red ginseng, notoginseng, Panax japonicus, and Panacis majoris rhizoma) have different bioactivities from each other, even under different dosages, but their chem. compositions are very similar; so the question is, what is the primary effective substance induced the different efficacy, and how to identify them from a group of chem. constituents′. The goal of this research was to provide a strategy to determine the effective substance in Panax genus medicinal plants responsible for the anticoagulant response. This research used ultra-high performance liquid chromatog. coupled with mass spectrometry (UPLC-MS) to analyze the saponin chem. compositions of different concentration ethanol extraction of notoginseng and the ginseng genus medical plant 75% ethanol extraction (Panax ginseng, red ginseng, Panax japonicus, Panacis majoris rhizome), and used four coagulation factors (PT, TT, APTT, Fib) to evaluate the anticoagulant activity of the extracts Gray correlation anal. was applied to establish the spectral effect relationship and give the anticoagulant potency of different saponins. Network pharmacol. and mol. docking were adopted to clarify and verify the possible mechanisms of anticoagulant action. The results showed that the blood physiol. regulation activities of Panax medicinal plants were different according to the solvent concentration, processing, species and dosage. Overall, the most suitable solvent for extraction of SQ was 75% ethanol; At low dosage (10-100 mg/mL), the anticoagulant effect of Panax medical plants was: ZJS > ZZS > SQ > RS > HS, and at high doses (100-1000 mg/mL) was: SQ > ZJS > ZZS > RS > HS. GRA and mol. docking results showed the contribution of some components (NG-R2, NG-Fc/G-Ra1/G-Ra2, G-Rc, G-Rk3, and G-Rh4) to the whole anticoagulant activity of the drug were increased, while the effect of CS-IVa was just decreased with the increase of dosage; the anticoagulant effect of G-Rg3 (the main anticoagulant component) is mainly related to the targets F2, AR, RHO, ACR, MB, GZMB, B2M, CA2, CAT, and PAPOLA. This study determined the effective substance of anti-coagulation of ginseng genus herbal medicines and the regulation of different anticoagulant effects of TCM by changing various influencing conditions, including processing method, extraction method, and dose. It also provided an effective strategy for effective substances identification of multicomponent, multifunction, and multipurpose herbal medicine.

Dietary inulin increases Lactiplantibacillus plantarum strain Lp900 persistence in rats depending on the dietary-calcium level was written by Fuhren, Jori;Schwalbe, Markus;Roesch, Christiane;Nijland, Reindert;Wels, Michiel;Schols, Henk A.;Kleerebezem, Michiel. And the article was included in Applied and Environmental Microbiology in 2021.COA of Formula: C18H32O16 This article mentions the following:

Synbiotics are food supplements that combine probiotics and prebiotics to synergistically elicit health benefits in the consumer. Lactiplantibacillus plantarum strains display high survival during transit through the mammalian gastrointestinal tract and were shown to have health-promoting properties. Growth on the fructose polysaccharide inulin is relatively uncommon in L. plantarum, and in this study we describe FosE, a plasmid-encoded β-fructosidase of L. plantarum strain Lp900 which has inulin-hydrolyzing properties. FosE contains an LPxTG-like motif involved in sortase-dependent cell wall anchoring but is also (partially) released in the culture supernatant. In addition, we examined the effect of diet supplementation with inulin on the intestinal persistence of Lp900 in adult male Wistar rats in diets with distinct calcium levels. Inulin supplementation in high-dietary-calcium diets significantly increased the intestinal persistence of L. plantarum Lp900, whereas this effect was not observed upon inulin supplementation of the low-calcium diet. Moreover, intestinal persistence of L. plantarum Lp900 was determined when provided as a probiotic (by itself) or as a synbiotic (i.e., in an inulin suspension) in rats that were fed unsupplemented diets containing the different calcium levels, revealing that the synbiotic administration increased bacterial survival and led to higher abundance of L. plantarum Lp900 in rats, particularly in a low-calcium-diet context. Our findings demonstrate that inulin supplementation can significantly enhance the intestinal delivery of L. plantarum Lp900 but that this effect strongly depends on calcium levels in the diet.

Utilization of GC-MS untargeted metabolomics to assess the delayed response of glufosinate treatment of transgenic herbicide resistant (HR) buffalo grasses (Stenotaphrum secundatum L.) was written by Boonchaisri, Siriwat;Stevenson, Trevor;Dias, Daniel A.. And the article was included in Metabolomics in 2020.SDS of cas: 470-69-9 This article mentions the following:

A major aim of this present work is to characterize and evaluate the metabolic alterations which may arise from a genetic transformation of HR buffalo grasses by comprehensively using gas chromatog.-mass spectrometry (GC-MS) based untargeted metabolomics. Plants were either sprayed with 1, 5, 10 and 15% volume/volume of glufosinate to evaluate the visual injuries or submerged in 5% volume/volume of glufosinate 3 days prior to a GC-MS based untargeted metabolomics anal. Results identified 199 metabolites with only 6 of them (cis-aconitic acid, allantoin, cellobiose, glyceric acid, maltose and octadecanoic acid) found to be statistically significant (p < 0.05) between the HR and wild type buffalo grass varieties compared to the control experiment As expected, glufosinate treatment caused significant metabolic alterations in sensitive wild type, with the up-regulation of several amino acids (e.g. phenylalanine and isoleucine) which was likely due to glufosinate-induced senescence. The aminoacyl-tRNA biosynthetic pathway was identified as the most significant enriched pathway as a result of glufosinate effects because a number of its intermediates were amino acids. The current metabolomics analyses not only confirmed the effects of glufosinate to up-regulate free amino acid pools in the sensitive wild type but also several alterations in sugar, sugar phosphate and organic acid metabolism have been reported. In the experiment, the researchers used many compounds, for example, (2R,3R,4S,5S,6R)-2-(((2S,3S,4S,5R)-2-((((2R,3S,4S,5R)-3,4-Dihydroxy-2,5-bis(hydroxymethyl)tetrahydrofuran-2-yl)oxy)methyl)-3,4-dihydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)oxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol (cas: 470-69-9SDS of cas: 470-69-9).

(2R,3R,4S,5S,6R)-2-(((2S,3S,4S,5R)-2-((((2R,3S,4S,5R)-3,4-Dihydroxy-2,5-bis(hydroxymethyl)tetrahydrofuran-2-yl)oxy)methyl)-3,4-dihydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)oxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol (cas: 470-69-9) belongs to tetrahydrofuran derivatives. Tetrahydrofuran (THF), or oxolane, is mainly used as a precursor to polymers. Being polar and having a wide liquid range, THF is a versatile solvent. Tetrahydrofuran can also be produced, or synthesised, via catalytic hydrogenation of furan. This process involves converting certain sugars into THF by digesting to furfural. An alternative to this method is the catalytic hydrogenation of furan with a nickel catalyst.SDS of cas: 470-69-9

Combining Mass Spectrometry and NMR Improves Metabolite Detection and Annotation was written by Bhinderwala, Fatema;Wase, Nishikant;DiRusso, Concetta;Powers, Robert. And the article was included in Journal of Proteome Research in 2018.Recommanded Product: 470-69-9 This article mentions the following:

Despite inherent complementarity, NMR spectroscopy (NMR) and mass spectrometry (MS) are routinely sep. employed to characterize metabolomics samples. More troubling is the erroneous view that metabolomics is better served by exclusively using MS. Instead, the authors demonstrate the importance of combining NMR and MS for metabolomics by using small chem. compound treatments of Chlamydomonas reinhardtii as an illustrative example. A total of 102 metabolites were detected (82 by gas chromatog.-MS, 20 by NMR, and 22 by both techniques). Out of these, 47 metabolites of interest were identified: 14 metabolites were uniquely identified by NMR, and 16 metabolites were uniquely identified by GC-MS. A total of 17 metabolites were identified by both NMR and GC-MS. In general, metabolites identified by both techniques exhibited similar changes upon compound treatment. In effect, NMR identified key metabolites that were missed by MS and enhanced the overall coverage of the oxidative pentose phosphate pathway, Calvin cycle, tricarboxylic acid cycle, and amino acid biosynthetic pathways that informed on pathway activity in central carbon metabolism, leading to fatty-acid and complex-lipid synthesis. The authors’ study emphasizes a prime advantage of combining multiple anal. techniques: the improved detection and annotation of metabolites. In the experiment, the researchers used many compounds, for example, (2R,3R,4S,5S,6R)-2-(((2S,3S,4S,5R)-2-((((2R,3S,4S,5R)-3,4-Dihydroxy-2,5-bis(hydroxymethyl)tetrahydrofuran-2-yl)oxy)methyl)-3,4-dihydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)oxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol (cas: 470-69-9Recommanded Product: 470-69-9).

Tetrahydrofurans and furans are important oxygen-containing heterocycles that often exhibit interesting properties for biological applications or applications in the cosmetic industry. Tetrahydrofuran (THF) is primarily used as a precursor to polymers including for surface coating, adhesives, and printing inks.Recommanded Product: 470-69-9
