Chitin (β-1,4-linked 2-acetamido-2-deoxy-D-glucose) is found throughout the biosphere. Its estimated production is 1010 to 1012 tons per year. Chitin is
The coordination of chitin synthesis and its degradation re-quires strict control of the participating enzymes for subsequent growth and development
4.1. Extraction of Chitin The primary commercial sources of chitin are crab and shrimp shells. The isolation of chitin begins
The descriptions and depictions of chitin and chitosan require several levels that are linked to the carbohydrate nature and the
6.1. Crystallography of Chitins The availability of chitin in the form of a solid polycrystalline material made it a substrate of
Chitosan is the collective name for a group of fully and partially deacetylated chitins. Their fraction of acetylation FA influences
8.1. Solubility of ChitinChitin occurs naturally partially deacetylated (with a low content of glucosamine units), depending on the sourceMathur &
9.1. Molecular Weight. A complete analysis of the molecular weight distribution by SEC using triple detection Brugnerotto et al., 2001 (viscosity, concentration, molecular
10.1. Complex formation with metalsChitosan exhibits good complexing ability throughout the involvement of the –NH2 groups along the chain, in specific
11.1. Chitin Derivatives Chitin displays properties such as biodegradability, and non-toxicity, which form the basis of many applications in bio-medicine, pharmacy,
The high interest in medical applications of chitosan and some of its derivatives are readily recognized. The cationic character of
