glyco amino acids
Glyco amino acids are carbohydrate derivatives containing both amino and carboxylic acid functionalities. Glyco amino acids and their derivatives exist in various forms with various biological activities in nature. Recently, to meet the increasing demand for discovering new molecules entities to develop new drugs and materials, many unnatural glyco amino acids also have been designed and synthesized by many research groups. The stereochemical arrangement of the substituents of the sugar ring, its ring-size as well as the presence of additional functional groups provides a plethora of possible combinations.
