Abstract
Effect of overnight fasting on the concentration and the fatty acid composition of glycerolipids was examined in the tissues of male rat.
The concentration of liver phospholipid was increased after fasting, whereas no significant changes were found in the other tissues.
In liver, heart, kidney and adrenal, content of linoleate was decreased and the arachidonate increased on fasting. It was also observed that percentages of docosapentaenoate (ω6) was increased in testicular triglyceride and oleate in lung triglyceride. Percentage of linoleate was decreased in triglyceride of epididymal adipose tissue, but no significant change was observed in the fatty acid composition in plasma free fatty acid.
From these data, it was clearly showed that the concentration and composition of glycerolipids in rats were characteristically altered with a mild modulation as overnight fasting.
