Protocol presents a method that allows rapid determination of the monosaccharide composition of glycans, glycoproteins, and proteoglycans that contain (or are suspected to contain) phosphorylated sugars. (For samples that do not contain phosphorylated sugars see Monosaccharide Analysis by Methanolysis.) - [Read Monosaccharide Analysis of Phosphorylated Sugars by Methanolysis and Diazomethane Methylation]
