[Use of [1-14C]linolenic acid in lipid synthesis in ruminant tissues during the prenatal and postnatal periods of development in vitro].

Radioactivity of phospholipids, triglycerides, free and esters-bound cholesterol synthetized by homogenates of the liver, skeletal muscle and adipose tissues from the fetuses and adult cattle after in vitro incubation with [1-14C] linolenic acid was higher than that in the adult cattle. In the liver, skeletal muscle and adipose tissues of fetuses and adult animals [1-14C] linolenic acid is much utilized for the synthesis of phospholipids than for the synthesis of triglycerides and cholesterol esters, in particular.
