Application
Glycerol kinase (glpK) was used to study the effects of pain controlling neuropeptides on human fat cell lipolysis.
Biochem/physiol Actions
Glycerol kinase catalyzes tge MgATP-dependent phosphorylation of glycerol to produce sn-glycerol-3-phosphate and is the rate limiting enzyme in the utilization of glycerol. It is also subject to feedback regulation by fructose-1,6-bisphosphate.

Physical form
Partially purified lyophilized powder, balance is primarily salts and EDTA.
Other Notes
One unit will convert 1.0 μmole of glycerol and ATP to L-α-glycerophosphate and ADP per min at pH 9.8 at 25 °C in a coupled system with PK/LDH.
