A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, Recommanded Product: 5-Hydroxyindole, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 1953-54-4, Name is 5-Hydroxyindole, molecular formula is C8H7NO. In a Article, authors is Fuller，once mentioned of 1953-54-4
Four weeks after a single intraperitoneal injection of 4-chloroamphetamine hydrochloride (0.1 mM/kg) into rats, brain serotonin and 5-hydroxyindoleacetic acid levels were still depressed to approximately half the control values, though tryptophan levels in brain were normal. Serotonin turnover in brain was likewise depressed to about half of the control rate as measured by (a) the rate of serotonin accumulation after monoamine oxidase inhibition and (b) the rate of 5-hydroxyindoleacetic acid accumulation after probenecid administration to block its efflux. Despite this decreased turnover rate, the capacity of the brain to synthesize 5-hydroxyindoles, as indicated by the increases in serotonin and 5-hydroxyindoleacetic acid after the injection of various doses of L-tryptophan, was not altered.
Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. I hope my blog about is helpful to your research. Recommanded Product: 5-Hydroxyindole
