3 Terms and definitions

The following terms and definitions apply to this document. 3.1 Chitinase activity unit chitinaseactivityunit At 37 ° C, pH 6.0, β-N-acetylglucosaminidase-assisted two-step reaction catalyzed the formation of 1 mg N-B per minute The amount of chitinase in acylglucose is one unit of activity, in units of U.

4 principle

Chitinase rapidly catalyzes the hydrolysis of chitin to N-acetylglucose or disaccharides and oligosaccharides composed of N-acetylglucose, disaccharides and Oligosaccharides continue to be hydrolyzed with N-acetylglucosaminidase to N-acetylglucose, which is detectable by absorbance, Calculated N-acetyl glucose production measured enzyme activity.
