Websoluble in water. In nature, chitin forms complex skeletons that form in a multi-step process. Chitin molecules are synthesized by transglycosylating, membrane-bound enzymes known as chitin synthetase EC 2.4.1.16, which use uridine diphosphate-N-acetylglucosamine (UDPGlcNAc) as a substrate. In fungi, for example, this happens Chitin is a modified polysaccharide that contains nitrogen; it is synthesized from units of N -acetyl- D -glucosamine (to be precise, 2- (acetylamino)-2-deoxy- D -glucose).
