Penta-N-acetylchitopentaose（Cat No.:R000356）is an oligosaccharide composed of five β-(1→4)-linked N-acetyl-D-glucosamine (GlcNAc) units, derived from the partial hydrolysis of chitin. It represents a mid-length chito-oligosaccharide that retains the structural features of natural chitin while offering improved solubility and bioactivity. This pentamer exhibits notable biological functions, including antimicrobial, antioxidant, and plant defense–stimulating activities. It is widely used in biomedical research, agriculture, and cosmetic formulations. Due to its size, Penta-N-acetylchitopentaose is ideal for studying structure–activity relationships in glycoprotein interactions, immune responses, and enzymatic degradation by chitinases or chitosanases.
