Presence of glycerokinase in guinea pig mammary gland and the incorporation of glycerol into glycerides

Abstract

The presence of glycerokinase in homogenates of mammary tissue from lactating guinea pigs is demonstrated. It has been shown that α-glycerophosphate-C14 (chromatographically identified) is formed from glvcerol-1,3-C14 in the presence of homogenate. This reaction requires ATP and Mg++. Glycerol-C14 is incorporated into the glycerol moiety of glycerides via α-glycerophosphate. G1ucose-C14 can also serve as a source of glyceride glycerol.
