HUMAN NUTRITION

Detailed explanation-1: -Chitin is the main structural amino polysaccharide found in the exoskeleton of invertebrates, crustaceans, and insects [90, 91]. Chitosan, a natural poly-N-acetyl-glucosamine, is derived from chitin via alkaline deacetylation [91].

Detailed explanation-2: -Chitin is an important component of the exoskeleton of eukaryotes which are generally devoid of bones. Chitin provides a protective covering to organisms that secrete it. The hydrogen bonds between the chitin monomers make it a strong material. Chitin is a polymer but not a protein.

Detailed explanation-3: -Chitin is a linear polysaccharide of the amino sugar N-acetyl glucosamine. It is present in the extracellular matrix of a variety of invertebrates including sponges, molluscs, nematodes and arthropods and fungi.

Detailed explanation-4: -Chitin is a large, structural polysaccharide made from chains of modified glucose. Chitin is found in the exoskeletons of insects, the cell walls of fungi, and certain hard structures in invertebrates and fish. In terms of abundance, chitin is second to only cellulose.
