A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, Formula: C10H14O5V, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 3153-26-2, Name is Vanadyl acetylacetonate, molecular formula is C10H14O5V. In a Patent, authors is ，once mentioned of 3153-26-2
VANADIUM COMPLEXES WITH HYDRAZIDE-HYDRAZONES, PROCESS FOR THEIR PREPARATION, PHARMACEUTICAL FORMULATIONS AND THE USE OF THEREOF.
Vanadium complexes of the general formula M[VX(ONO)y(L)n]-mS, wherein X is oxygen or is absent, L is L1or L2, wherein Li represents a halogen anion or a neutral molecule or deprotonated solvent selected from the group comprising C1-C12 alcohols and/or water, and L2 is a neutral or anionic NN, NO or OO-donor ligand selected from the group consisting of: polypyridine, 1,10-phenanthroline, pyrones, quinoline or pyridine carboxylic acids, S is a neutral solvent molecule selected from the group consisting of C 1-C4 alcohols, water or sulfuric acid, M may be absent, and when present it is monocharged alkali metal cation, ammonium cation, alkylammonium cation, and the letters O and N represent atom, by which the ligand is bound to vanadium. The invention also includes a method for making vanadium complexes, pharmaceutical preparations containing these complexes and the use of the complexes.
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. Formula: C10H14O5V
