WebDec 1, 2004 · The solvent kinetic isotope effects (SKIE) on the yeast α-glucosidase-catalyzed hydrolysis of p-nitrophenyl and methyl-d-glucopyranoside were measured at 25 °C.With p-nitrophenyl-d-glucopyranoside (pNPG), the dependence of k cat /K m on pH (pD) revealed an unusually large (for glycohydrolases) solvent isotope effect on the pL-independent … Web1 day ago · Introduction. Naturally occurring lithium element consists of two stable isotopes, 6 Li & 7 Li, and each isotope plays a critical application in nuclear science and industry. 7 LiOH is usually used as a pH controller in the pressurized-water reactor (PWR) to slow down the corrosion of the pressure vessel wall. In this process, 7 Li needs to be enriched to a …
