The disaccharide repeating unit in chitin, differing from cellobiose only in the presence of an N-acetylamino group on carbon-2 in place of the hydroxyl group. However, the nonacetylated form is often also referred to as chitobiose.

As the second-most abundant biopolymer after cellulose, chitin is mainly synthesized via a biosynthetic process by an enormous number of living organisms such as shrimp, crab, tortoise, and insects and can also be synthesized by a nonbiosynthetic pathway through chitinase-catalyzed polymerization of a chitobiose oxazoline derivative.
