title: Effects of fasting on plasma lipids and cholesterol esterification in plasma, liver and intestinal mucosa in the char (Salmo alpinus L.).
abstract: 1. CoA-dependent cholesterol esterification, measured as esterification of 3H-cholesterol, was demonstrated in homogenates of liver and intestinal mucosa of the char (Salmo alpinus L.). 2. Plasma concentration of triacylglycerols, unesterified and total cholesterol were significantly reduced to 43, 58 and 72% of the control values, respectively, after 6 weeks fasting. 3. The rate of cholesterol esterification in plasma and liver homogenate was significantly lower in the fasted fish compared to the controls, but the esterification activity in the homogenate of intestinal mucosa increased twofold in the fish fasted for 6 weeks.
