Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction. In homogeneous catalysis, catalysts are in the same phase as the reactants.14215-68-0, 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.name: N-((2S,3R,4R,5R,6R)-2,4,5-Trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-3-yl)acetamide.
