WebMay 15, 2024 · Chitin and cellulose are the two most abundant, inexhaustible, and renewable natural resources for human beings. Chitin is widely present in fungi and algae's cell wall, the shell of arthropods such as shrimp, crabs, insects, and the shell and cartilage of shellfish mollusks (Ifuku & Saimoto, 2012; Jones et al., 2024 ). 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 … See more The English word "chitin" comes from the French word chitine, which was derived in 1821 from the Greek word χιτών (khitōn) meaning covering. A similar word, "chiton", refers to a marine animal with a … See more Chitin was probably present in the exoskeletons of Cambrian arthropods such as trilobites. The oldest preserved chitin dates to the Oligocene, about 25 million years ago, consisting of a scorpion encased in amber. See more How chitin interacts with the immune system of plants and animals has been an active area of research, including the identity of key receptors with which chitin interacts, whether the size of chitin particles is relevant to the kind of immune response triggered, … See more The structure of chitin was determined by Albert Hofmann in 1929.
