Abstract
It is now clear that not all the biological effects of insulin are caused by an increased rate of transport of sugars and amino acids across the cell membrane. One well documented effect that does not depend upon a stimulation of glucose metabolism is the antilipolytic action in adipose tissue which can be observed when rat epididymal fat pads are incubated in a glucose-free medium (1). Insulin has also been shown to increase the fraction in the independent (I) form of glycogen synthetase in rat diaphragm incubated in a medium without added substrate (2). Recently, Jungas (3) reported that insulin increased the percentage of the I form of glycogen synthetase in incubated adipose tissue and decreased the activity of adipose tissue glycogen Phosphorylase assayed without added 5′-AMP.
