Infobox references

Glycerol 2-phosphate is the conjugate base of phosphoric ester of glycerol. It is commonly known as β-glycerophosphate or BGP. Unlike glycerol 1-phosphate and glycerol 3-phosphate, this isomer is not chiral. It is also less common.

Applications

β-Glycerophosphate is an inhibitor of the enzyme serine-threonine phosphatase. It is often used in combination with other phosphatase/protease inhibitors for broad spectrum inhibition.[1][2]

β-Glycerophosphate is also used to drive osteogenic differentiation of bone marrow stem cells in vitro.[3]

β-Glycerophosphate is used to buffer M17 media for Lactococcus culture in recombinant protein expression.[4]
