Stereospecific biosynthesis of triacylglycerols in mammary glands from lactating rats.

S M Cooper, M R Grigor.   

Abstract

Microsomal plus cytosol preparations from the mammary gland of lactating rats are capable of incorporating palmitic acid and oleic acid into triacylglycerols. These triacylglycerols are similar in structure to those found in rat milk, where palmitic acid tends to be confined to the sn-2-position of the glycerol. Both glycerol 3-phosphate and dihydroxyacetone phosphate function as acyl acceptors. The enzymic synthesis of triacylglycerols appears in late pregnancy, increases rapidly during early lactation, but disappears within 3 days of weaning.
