α-D-Mannose 1-Phosphate is used in the synthesis of non-natural mannoglucans by α-glucan phosphorylase-catalyzed enzymatic copolymerization;Also, it is derived from D-Mannose, which is a carbohydrate that is important in the glycosylation of molecules in a variety of cellular processes. It is involved in N and O glycosylation of bovine why protein products, used in infant formulas. It is also responsible for the O-glycosylation of the T helper cell-derived cytokine interlukin-17A, an important cell-signaling molecule.
