Reference of 453-20-3, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 453-20-3, molcular formula is C4H8O2, introducing its new discovery.
Compounds of Formula (I) or pharmaceutically acceptable salt thereof, a pharmaceutical compositions comprising these compounds, the use of these compounds and compositions in the treatment of diseases in which LRRK-2 kinase is involved.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 453-20-3 is helpful to your research. Reference of 453-20-3
