BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Chitin is the most abundant aminopolysaccharide polymer occurring in nature, and is the building material that gives strength to the exoskeletons of crustaceans, insects, and the cell walls of fungi.

Detailed explanation-2: -Introduction. Chitin is commonly found in the shells of crustaceans, the exoskeleton of various insects, cell walls of coralline algae and many other marine organisms, fungi, plants, and bacteria [1, 2, 3].

Detailed explanation-3: -Chitin is one of the most important biopolymers in nature. It is mainly produced by fungi, arthropods and nematodes. In insects, it functions as scaffold material, supporting the cuticles of the epidermis and trachea as well as the peritrophic matrices lining the gut epithelium.

Detailed explanation-4: -Chitin is a long-chain unbranched polysaccharide made of -1, 4-linked anhydro-2-acetamido-2-deoxy-d-glucose (GlcNAc) which forms crystalline fibrillar structures following association of adjacent chains through hydrogen bonds between the N–H and the CO groups.
