In vitro age-dependent incorporation of [1- 14C]acetate into lipid subclasses in rat ventral prostate

1. 1. The [l- 14C]acetate incorporation into different lipid subclasses by the rat prostate gland was lineal between 20 and 80 mg of wet tissue. 2. 2. The in vitro [l- 14C]jacetate incorporation into lipid subclasses was a development-dependent process. The highest values of [l-l- 14C]jacetate incorporation into triacylglycerols, free cholesterol and esterified cholesterol were observed at puberty, but radioactivity incorporation into phospholipids was similar in both prepuberty and puberty, then decreasing in maturity. 3. 3. The relationship between triacylglycerols, free cholesterol and esterified cholesterol with respect to total lipids was about 12, 10 and 3.5%, respectively, values being maintained during the animal development. 4. 4. The in vitro [l- 14C]acetate incorporation into lipid subclasses in castrated rats decreased considerably as compared with normal rats.
