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.
