Application

Glycerol kinase has been used along with adenosine triphosphate (ATP) for the conversion of glycerol to glycerol-3 phosphate (glycerol-3P) in white adipose tissue (WAT) adipocyte samples by label distribution method. It has also been used along with adenosine triphosphate (ATP) in the derivatization of glycerol to sn-glycerol-3 phosphate (glycerol-3P).

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

Suspension in 3.1 M (NH₄)₂SO₄ pH 7.3, with 1% BSA and 2% trehalose

Unit Definition

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.
