Fatty acid labeled chyle was administered iv to ad lib fed rats. At intervals from 1 hr to 50 days later rats were killed and pieces of their parametrial adipose tissue were incubated in vitro with norepinephrine. The specific radioactivity of the mobilized free fatty acids was compared to that of tissue glycerides and that of tissue free fatty acids. The results indicate that fatty acids taken up by the adipose tissue do not mix immediately with the bulk of tissue lipids and that the mobilized free fatty acids do not pass through the tissue free fatty acid pool.
