A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 14215-68-0, Name is N-((2S,3R,4R,5R,6R)-2,4,5-Trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-3-yl)acetamide, molecular formula is C8H15NO6.

Commercial non-chitinase enzymes from Aspergilus niger, Acremonium cellulolyticus and Trichoderma viride were investigated for potential utilization in the preparation of 2-acetamido-2-deoxy-D-glucose (N-acetyl-D-glucosamine, GlcNAc) from chitin. Among the tested enzymes, cellulase A. cellulolyticus exhibited highest chitinolytic activity per weight toward amorphous chitin and beta-chitin from squid pen. The optimum pH of the enzyme was 3 where it produced two major hydrolytic products, GlcNAc and N,N?-diacetylchitobiose ([GlcNAc]2). The product ratio, GlcNAc:[GlcNAc]2, increased while the total yield decreased as the pH was raised from 3. All of the [GlcNAc]2 produced at pH 3 can be converted in situ to GlcNAc by mixing cellulase A. cellulolyticus with one of several other enzymes from A. niger resulting in a higher yield of GlcNAc. An appropriate mixing ratio of cellulase A. cellulolyticus to another enzyme was 9:1 (w/w) and an optimum substrate concentration was 20 mg/mL.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Recommanded Product: 14215-68-0. In my other articles, you can also check out more blogs about 14215-68-0
