Rapid inhibition of lipogenesis in vivo in lactating rat mammary gland by medium- or long-chain triacylglycerols and partial reversal by insulin.

Abstract

An intragastric load of medium- or long-chain triacylglycerols inhibited lipogenesis in lactating rat mammary gland in vivo by 82 or 89% respectively. This inhibition was reversed partially by insulin administration. Long-chain triacylglycerols inhibited hepatic lipogenesis in vivo but medium-chain triacylglycerols increased it 2-fold. Glucose utilization in vitro by mammary gland acini from triacylglycerol-fed rat was normal.
