WebIn the computer science subfield of algorithmic information theory, a Chaitin constant ( Chaitin omega number) [1] or halting probability is a real number that, informally speaking, represents the probability that a randomly constructed program will halt. These numbers are formed from a construction due to Gregory Chaitin . 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 … 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, … 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 See more • Biopesticide • Chitosan • Chitobiose • Lorica • Sporopollenin • Tectin See more The structure of chitin was determined by Albert Hofmann in 1929. Hofmann hydrolyzed chitin using a crude preparation of the enzyme chitinase, which he obtained from the snail Helix pomatia. Chitin is a modified polysaccharide that contains nitrogen; it is See more Agriculture Chitin is a good inducer of plant defense mechanisms for controlling diseases. It has potential for use as a soil fertilizer or conditioner to improve fertility and plant resilience that may enhance crop yields. Industrial See more WebChitin is a tough and resilient material that provides structural support and protection for these organisms. One of the key properties of chitin is its ability to form strong, flexible fibers. These fibers are responsible for the strength and rigidity of the exoskeletons of insects and other arthropods. cysto term
