Abstract
Influence of various dietary fats on lipid deposition in the liver of rats fed a wheat flour diet supplemented with lysine was investigated. The fat source in the diet was provided by coconut oil, shortening oil and soybean oil. The following results were obtained.
The liver of rats fed wheat flour diet containing coconut oil or soybean oil have a normal total lipid or triglyceride content, but when such diets were supplemented with lysine-HCl, total lipid or triglyceride content was remarkably increased. However, the concentration of total lipids or triglyceride in the liver of rats fed wheat flour diet supplemented with lysine-HCl was reduced when shortening oil was substituted for coconut oil or soybean oil. The concentration of liver triglyceride in rats fed a lysinesupplemented wheat flour diet decreased significantly by increasing the shortening oil content of the diet from 5 to 15%, but it did not change by increasing the soybean oil content of the diet from 5 to 15%. It was found that the fatty acid composition of triglyceride in liver of rats fed a lysinesupplemented wheat flour diet containing coconut oil or soybean oil was not significantly different to that of rats fed the wheat flour diet containing coconut oil.
