Sizing and Desizing of Cotton and Polyester Yarns Using Liquid and Supercritical Carbon Dioxide with Nonfluorous CO2-Philes as Size Compounds was written by Antony, Anu;Raj, Anila;Ramachandran, Jyothi P.;Ramakrishnan, Resmi M.;Wallen, Scott L.;Raveendran, Poovathinthodiyil. And the article was included in ACS Sustainable Chemistry & Engineering in 2018.Reference of 126-14-7 This article mentions the following:

In this work, we demonstrate a completely green and economically viable sizing and desizing process for cotton and polyester yarns using liquid and supercritical CO2 as alternative solvent systems and inexpensive, nonfluorous CO2-philes as size compounds The size performance of sucrose octaacetate (SOA), α-D-glucose pentaacetate (AGLU), and poly(ethylene glycol) (PEG) are studied. The mech. properties of the sized yarn, as well as the optical and electron microscopic studies, are carried out to evaluate the quality of sizing. It is shown that SOA is the most suitable candidate as the size compound as it provides the best surface coverage and improved mech. properties for the yarn, plausibly assisted by the formation of a smooth and glassy coating of SOA on the yarn. For AGLU and SOA, complete desizing is easily effected by virtue of their complete miscibility with liquid and supercritical CO2 at low pressures. It is observed that the desizing of the PEG-sized yarn is difficult due to the poor solubility of the size in the CO2-based solvent systems. The entire size materials and the solvent can be recycled, making it a zero-pollution technol. that can easily be translated into industry at an affordable cost. In the experiment, the researchers used many compounds, for example, (2R,3R,4S,5R,6R)-2-(Acetoxymethyl)-6-(((2S,3S,4R,5R)-3,4-diacetoxy-2,5-bis(acetoxymethyl)tetrahydrofuran-2-yl)oxy)tetrahydro-2H-pyran-3,4,5-triyl triacetate (cas: 126-14-7Reference of 126-14-7).

Metabolomics analysis of time-series human small intestine lumen samples collected in vivo was written by Folz, Jacob S.;Shalon, Dari;Fiehn, Oliver. And the article was included in Food & Function in 2021.Formula: C18H32O16 This article mentions the following:

The human small intestine remains an elusive organ to study due to the difficulty of retrieving samples in a non-invasive manner. Stool samples as a surrogate do not reflect events in the upper gut intestinal tract. As proof of concept, this study investigates time-series samples collected from the upper gastrointestinal tract of a single healthy subject. Samples were retrieved using a small diameter tube that collected samples in the stomach and duodenum as the tube progressed to the jejunum, and then remained positioned in the jejunum during the final 8.5 h of the testing period. Lipidomics and metabolomics liquid chromatog. tandem mass spectrometry (LC-MS/MS) assays were employed to annotate 828 unique metabolites using accurate mass with retention time and/or tandem MS library matches. Annotated metabolites were clustered based on correlation to reveal sets of biol. related metabolites. Typical clusters included bile metabolites, food metabolites, protein breakdown products, and endogenous lipids. Acylcarnitines and phospholipids were clustered with known human bile components supporting their presence in human bile, in addition to novel human bile compounds 4-hydroxyhippuric acid, N-acetylglucosaminoasparagine and 3-methoxy-4-hydroxyphenylglycol sulfate. Food metabolites were observed passing through the small intestine after meals. Acetaminophen and its human phase II metabolism products appeared for hours after the initial drug treatment, due to excretion back into the gastrointestinal tract after initial absorption. This exploratory study revealed novel trends in timing and chem. composition of the human jejunum under standard living conditions.

Fructooligosaccharides can be produced by direct enzymic conversion from sucrose-rich sugarcane syrup (SS) consisting of 58.93% sucrose yielding 21.28 g FOS/100 g sucrose. This study evaluated the prebiotic effect of unpurified/purified SS containing FOS for the modulation of the human intestinal microbial composition and short-chain fatty acid production The unpurified and purified FOS substrates, which were a mixture of 1-kestose, nystose and 1F-fructosylnystose, were supplemented into human fecal culture using a pH-controlled batch fermentation system and significantly increased the Bifidobacterium counts after 5 h fermentation, while Bacteroides/Prevotella counts were highest throughout 24 h fermentation Meanwhile, Lactobacillus/Enterococcus exhibited a slight increase after 5 h fermentation before reaching a plateau afterwards. The steady Bacteroides/Prevotella growth and increased Bifidobacterium population promoted an increase in the production of short-chain fatty acids acetate (58 ± 2.70 mM), propionate (9.19 ± 5.94 mM) and butyrate (7.15 ± 2.28 mM). These results provide evidence that representative gut microbiota could utilize the enzymically synthesized FOS to generate short-chain fatty acids as metabolites in pH-controlled conditions, thus FOS from SS are a potential prebiotic ingredient for foods and health drinks.

A sterically strained ionic Bronsted pair complex obtained from a sterically bulky base 2,4,6-tri-tert-butylpyridine and hydrochloric acid unusual reactivity to the anionic chloride. The complete shielding of the cationic [N-H]+ by the bulky ortho-tert-Bu groups weakens the possible hydrogen-bonding interactions with the chloride anion, and the [N-H]+···Cl distance is unusually longer (3.10 Å). This results in strained/frustrated electrostatic interactions between the ion-pair, thus infusing an increased reactivity in both of the ions, which results in the activation of a third mol. like thiol via hydrogen-bonding. This intriguing weak interaction-based reactivity has been utilized to develop an organocatalytic synthesis of 2-deoxy-β-thioglycosides from glycals. While the 1H NMR studies showcase the diamagnetic activation of thiols in the presence of the catalyst, the ESR (EPR) studies reveal the generation of a radical species that suggests a possible frustrated radical pair catalysis. Besides, IR spectroscopic studies explain the intriguing influence of size/charge d. of the anion on the solvation-insusceptible, cationic [TTBPyH]+ and on the observed reactivity.

Impact of low molecular weight excipient octaacetylmaltose on the liquid crystalline ordering and molecular dynamics in the supercooled liquid and glassy state of itraconazole was written by Kaminska, E.;Tarnacka, M.;Kolodziejczyk, K.;Dulski, M.;Zakowiecki, D.;Hawelek, L.;Adrjanowicz, K.;Zych, M.;Garbacz, G.;Kaminski, K.. And the article was included in European Journal of Pharmaceutics and Biopharmaceutics in 2014.Synthetic Route of C28H38O19 This article mentions the following:

Different exptl. and theor. techniques were applied to investigate basic phys. properties of very stable and homogeneous solid dispersions formed by itraconazole and octaacetylmaltose. Differential scanning calorimetry as well as semi-empirical calculations have indicated that liquid crystalline ordering in itraconazole was completely suppressed in the binary mixtures Mol. dynamics studies with the use of broadband dielec. spectroscopy have shown that the width of the structural relaxation process becomes smaller and fragility drops in solid dispersions with respect to the pure itraconazole. Moreover, the dynamics of secondary relaxation processes was affected by acetylated maltose. As demonstrated, β- and γ-secondary modes shift to higher and lower frequencies, resp. On the other hand, aging experiments revealed that isostructural relaxation times in the glassy state become systematically longer with the addition of modified carbohydrate. This is a very important finding in the context of the current discussion on the factors affecting phys. stability of easily crystallizing APIs. It seems that beside intermol. interactions and local reorientation, the global mobility might control the crystallization of amorphous solid dispersions. Finally, we have demonstrated that itraconazole in binary mixtures dissolves faster and to greater extent with respect to the crystalline and amorphous form of this API.

Five strains of probiotic; Lactobacillus acidophilus, Lactobacillus casei, Lactobacillus plantarum, Leuconostoc mesenteroides, and Bifidobacterium longum were targeted for enhancing B-group vitamins and fructo-oligosaccharides (FOS) and raffinose family oligosaccharides (RFO) of cashew apple juice (CAJ) that is an underutilized byproduct from cashew nut processing. Although fermentation by Lb. acidophilus and Lb. casei resulted in increasing B-group vitamins contents (19.25% and 23.11%, resp.) than fermented CAJ with others probiotic, vitamin B2 levels of fermented CAJ were not different significantly. Results also indicated total sugar contents of fructose, glucose, galactose, sucrose, melibiose, and maltotriose were decreased during 48 h of fermentation The CAJ fermented with Lb. acidophilus and Lb. plantarum had higher oligosaccharide contents (RFO and FOS).

Garlic (Allium sativum L.) is a vegetable known worldwide, mainly for its characteristic aroma and flavor and for exhibiting several medicinal properties. This culture has significant economic and social relevance in the world agricultural scenario. Most of the garlic production is sold in fresh bulbs, where for some countries the more purple skin bulbs are more valued in the market. However, there is still no consensus about the factors that intensify the purple color of the garlic bulbs. Here, we employed gas chromatog.-mass spectrometry-based untargeted metabolomics to study the metabolome of dark and light purple garlics. Multivariate statistical anal. revealed distinct metabolite signatures between these garlic groups. As metabolic changes play an important factor in changes in the phenotype of cells or an organism, this report presents a fundamental approach for supporting garlic producers in understanding the factors that intensify the purplish color of garlic bulbs, paving the way for safer garlic production with dark purple bulbs. In addition, the medicinal properties of dark purple garlic were greater than that of the light purple garlic, presenting greater abundance in organosulfur compounds Overall, the data suggest that some organic acid and fatty acids such as malonic acid and docosanoic acid are the key differentiating factors between dark and light purple garlics. 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: 470-69-9Name: (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).

(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 has many industry uses as a solvent including in natural and synthetic resins, high polymers, fat oils, rubber, polymer. Tetrahydrofuran reaction with hydrogen sulfide: In the presence of a solid acid catalyst, tetrahydrofuran reacts with hydrogen sulfide to give tetrahydrothiophene.Name: (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
