Vorschrift

N-Acetylhexosamine dialdose may, for example, be manufactured by oxidation of the 6-position of N-acetylhexosamine either chemically or enzymatically. An example of the chemical oxidation is a Fenton method where oxidation is carried out with hydrogen peroxide in the presence of a ferrous salt while that of the enzymatic oxidation is an oxidation using galactose oxidase [EC 1.1.3.9; Cooper, et al.; The Journal of Biological Chemistry, volume 234, pages 445-448 (1959)]. Oxidation of N-acetyl-D-galactosamine with galactose oxidase gives N-acetylgalactosamine dialdose.
