Biosynthesis, Turnover, and Functions of Chitin in Insects
Chitin (C8H13O5N)n (/ˈkaɪtɪn/ KY-tin) is a long-chain polymer of N-acetylglucosamine, an amide derivative of glucose. Chitin is probably the second most abundant polysaccharide in nature (behind only cellulose); an estimated 1 billion tons of chitin are produced each year in the biosphere. It is a primary component of cell walls in fungi (especially basidiomycetes and filamentous fun… WebApr 1, 2024 · Chitin biosynthesis occurs along the cytoplasmic side of the plasma membrane, and involves at least eight enzymes (as reviewed in Merzendorfer and … lit bit of heaven cupcakes
