Definition
D-mannose 6-phosphate, also known as mannose-6-phosphate disodium salt, is a member of the class of compounds known as hexose phosphates. Hexose phosphates are carbohydrate derivatives containing a hexose substituted by one or more phosphate groups. D-mannose 6-phosphate is soluble (in water) and a moderately acidic compound (based on its pKa). D-mannose 6-phosphate can be found in a number of food items such as bog bilberry, wild celery, common pea, and breadnut tree seed, which makes D-mannose 6-phosphate a potential biomarker for the consumption of these food products. D-mannose 6-phosphate may be a unique S.cerevisiae (yeast) metabolite. The M6P-tagged lysosomal enzymes are shipped to the late endosomes via vesicular transport. Enzyme replacement therapy (ERT) for several lysosomal storage diseases relies on this pathway to efficiently direct synthetic enzymes to the lysosome where each can metabolize its particular substrate. The pH in the late endosome can reach 6.0, which causes dissociation of M6P from its receptor. Upon release, the enzymes are ferried to their final destination in the lysosomes. The MPRs are packed into vesicles that bud off the late endosome and return to the "trans"-Golgi network. In this way, the MPRs can be recycled.
Belongs to the class of organic compounds known as hexose phosphates. These are carbohydrate derivatives containing a hexose substituted by one or more phosphate groups.
