D-Mannose 1-phosphate (CAS: 27251-84-9) is a normal metabolite intermediate in fructose and mannose metabolism. It is a substrate of phosphomannomutase 1 (PMM, EC 5.4.2.8), an enzyme necessary for the synthesis of GDP-mannose (a substrate for dolichol-linked oligosaccharide synthesis). PMM converts mannose 6-phosphate into mannose-1-phosphate. A deficiency of phosphomannomutase in carbohydrate-deficient glycoprotein syndrome (CDGS) type I is associated with a decreased synthesis of mannose 1-phosphate. CDGS is a group of autosomal recessively transmitted disorders in which abnormally glycosylated proteins are formed (PMID: 9451026, 8549746, 12729595). α-d-mannose 1-phosphate is a member of the class of compounds known as monosaccharide phosphates. Monosaccharide phosphates are monosaccharides comprising a phosphated group linked to the carbohydrate unit. α-d-mannose 1-phosphate is soluble (in water) and a moderately acidic compound (based on its pKa). α-d-mannose 1-phosphate can be found in a number of food items such as lettuce, beech nut, red beetroot, and japanese pumpkin, which makes α-d-mannose 1-phosphate a potential biomarker for the consumption of these food products.
