glycerol kinase

Also found in: Encyclopedia, Wikipedia.

glyc·er·ol ki·nase

an enzyme that catalyzes a reaction between ATP and glycerol to yield sn-glycerol 3-phosphate and ADP; in adipose tissue, the first and rate-limiting step in the synthesis of triacylglycerols; deficiency results in the disruption of adrenal, muscle, and/or liver and brain function.
Synonym(s): glycerokinase
