Chitin Biochemistry: Synthesis, Hydrolysis and Inhibition

WebChitin oligosaccharides (COS) are N -acetylglucosamine (GlcNAc) oligomers (DP = 2–6) with β-1,4-linkages, and are produced from chitin derived from crabs and shrimps by partial acid hydrolysis in a hydrochloride solution. COS can be produced by enzymatic hydrolysis of chitin using bacterial chitinase (EC 3.2.1.14) as well. WebAlthough no chitin synthesis inhibitor has been developed into a therapeutic drug to treat fungal infections in humans, a larger number of compounds have been successfully … As an insect grows it molts, growing a new exoskeleton under its old one and then shedding the old one to allow the new one to swell to a new size and harden. IGRs prevent an insect from reaching maturity by interfering with the molting process. This in turn curbs infestations because immature insects cannot reproduce. Because these IGRs work by interfering with an insect's molting process, they kill insects more slowly than traditional insecticides.
