[The effect of hydrocortisone on the synthesis of lipids from different precursors]

A study was made of the intensity of lipid synthesis in the liver and adipose tissue of rats following a single administration of hydrocortisone (3, 6, 24 and 48 hours) from various labeled precursors. In the liver the hormone stimulated the synthesis of lipids from the acetate-I-C14 and lactate 1,3-C14 but blocked the lipogenesis from glycerine-1,2-C14 and glucose-1-c14. In the adipose tissue hydrocortisone intensified the lipid synthesis from glucose-1-C14 only and inhibited the lipid synthesis from other precursors. The action mechanism of the hormone on the lipogenesis is considered in association with the primary intensification of gluconeogenesis in the liver.
