β-Glycerophosphate (sodium salt hydrate) is a potent protein phosphatase inhibitor [1].

Protein phosphatase is an enzyme that removes a phosphate group from the phosphorylated amino acid residue of its target protein. Protein phosphorylation is one of the most common protein posttranslational modifications.

β-Glycerophosphate is a potent protein phosphatase inhibitor that acts as a phosphate group donor in bone cell mineralization studies [1][3]. In MC3T3-E1, ROS 17/2.8, and chick osteoblast-like cells, β-Glycerophosphate did not affect the rate of anaerobic glycolysis, but increased the medium Pi levels, suggesting that β-Glycerophosphate was hydrolyzed by bone cells. The local increase in medium Pi concentration promoted rapid mineral deposition [1]. In human bone marrow stromal cells (HBMSC) and human osteoblasts (HOB), BMP-2 resulted in mineralization of their matrix in the presence of beta-glycerophosphate and ascorbic acid [3]. β-Glycerophosphate (10 mM) also accelerated calcification of cultured vascular smooth muscle cells through an alkaline phosphatase-related mechanism [4].
