Description and Uses

N-acetyl-D-galactosaminidase catalyzes the cleavage of N-acetylglucosamine (GlcNAc), the monomeric unit of the polymer chitin. 4-Nitrophenyl-N-acetyl-α-D-galactosaminide can be used as a chromogenic substrate for N-acetyl-D-galactosaminidase, generating a yellow solution upon cleavage.

p-Nitrophenyl 2-Acetamido-2-deoxy-α-D-galactopyranoside (cas# 23646-68-6) is a compound useful in organic synthesis.
