we used a new tracer technique , direct tracer injection of [ 1-14c ] palmitate-serum albumin into extracellular fluid ( ecf ) of epididymal fat pads , to study relative transport rates of ecf-free fatty acids ( ffa ) to cell-ffa and subsequent esterification to diglyceride fatty acid ( dgfa ) and triglyceride fatty acid ( tgfa ) in adipose tissue versus movement of ecf- and cell-ffa into the circulation of mice fed ad libitum or fasted 48 hr .
