(Science: enzyme) An enzyme that catalyses the formation of glycerol 3-phosphate from atp and glycerol. Dihydroxyacetone and l-glyceraldehyde can also act as acceptors; utp and, in the case of the yeast enzyme, itp and gtp can act as donors. It provides a way for glycerol derived from fats or glycerides to enter the glycolytic pathway.
