WebOct 11, 2024 · The natural abundance of chitin is second-most, after the cellulose. However, chitin is the most abundant polymer of natural origin . Chitin is an amino polysaccharide. Chemically, chitin is composed of β-1,4 linked 2-(acetylamino)-2-deoxy-d-glucose elements (Figure 4) [4,10,11]. The degree of acetylation is >90%. WebChitin is a copolymer of N -acetyl-glucosamine and N -glucosamine units randomly or block distributed throughout the biopolymer chain, depending on the processing method used to derive the biopolymer ( Khor and Lim, 2003 ). The biopolymer is termed chitin if the number of N -acetyl-glucosamine units is higher than 50%.
