Avanços recentes na química dos aminoaçúcares: ocorrência, biossíntese, síntese e aplicação

Química Nova
Amino sugars are chemical compounds that have a sugar backbone, in which one of the hydroxyl groups is replaced by an amino group. Derivatives of amine-containing sugars, such as N-acetylglucosamine, are also considered amino sugars.
