Is chitin a monomer or polymer
WebSep 15, 2024 · Chitin is a modified carbohydrate for containing nitrogen. It is made up of a linear polymer of N-acetyl-D-glucosamine monomers (C8H13O5N) n»1. Similar to cellulose, the monomers are linked to each other by β(1→4) glycosidic bond. In cellulose though, the monomers are glucose units. What animals have chitin? WebEven one kind of monomer can combine in a variety of ways to form several different polymers: for example, glucose monomers are the constituents of starch, glycogen, and cellulose. Hydrolysis. Polymers are broken down into monomers in a process known as hydrolysis, which means “to split water,” a reaction in which a water molecule is used ...
