One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, COA of Formula: C28H30O4, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 125-20-2, Name is Thymolphthalein, molecular formula is C28H30O4
Hyperthermostable alkaline lipase from Bacillus sonorensis 4R was purified and characterized. The enzyme production was carried out at 80C and 9.0 pH in glucose-tween inorganic salt broth under static conditions for 96 h. Lipase was purified by anion exchange chromatography by 12.15 fold with a yield of 1.98%. The molecular weight of lipase was found to be 21.87 KDa by SDS-PAGE. The enzyme activity was optimal at 80C with t 1 / 2 of 150 min and at 90C, 100C, 110C, and 120C; the respective values were 121.59 min, 90.01 min, 70.01 min, and 50 min. The enzyme was highly activated by Mg and t 1 / 2 values at 80C were increased from 150 min to 180 min when magnesium and mannitol were added in combination. The activation energy calculated from Arrhenius plot was 31.102 KJ/mol. At 80-120C, values of Delta H and Delta G were in the range of 28.16-27.83 KJ/mol and 102.79 KJ/mol to 111.66 KJ/mol, respectively. Lipase activity was highest at 9.0 pH and stable for 2 hours at this pH at 80C. Pretreatment of lipase with MgSOand CaSOstimulated enzyme activity by 249.94% and 30.2%, respectively. The enzyme activity was greatly reduced by CoCl CdCl HgCl CuCl Pb(NO PMSF, orlistat, oleic acid, iodine, EDTA, and urea.
One of the oldest and most widely used commercial enzyme inhibitors is aspirin, COA of Formula: C28H30O4, which selectively inhibits one of the enzymes involved in the synthesis of molecules that trigger inflammation. you can also check out more blogs about 125-20-2
