Abstract
In this study the nutritive efficiency of fatty acid fed with monoglyceride and effects exercised by them upon the living body were investigated in rats. The diets containing ordinary content (6%) of experimental lipid, prepared from cotton seed oil, were given to young male rats for a fairly long time (six months). The following results were obtained.
1) The intestinal absorption of lipids and the food efficiency of the diet containing fatty acid with monoglyceride were equal to the diet containing triglyceride.
2) The weight gains of rats fed by fatty acid with monoglyceride were also equal to the rats fed by triglyceride throughout the experimental period. And the reduction of the growth rats which had seen in the previous experiment was not observed.
3) The increase of liver weight of rats and the abnormalities in pathological examination were hardly observed. On the other hand, the effects on the rats fed by pentadecanoic acid (C15FA) as a part of fatty acid were investigated. The results were as follows. The growth rate of the rats fed by pentadecanoic acid was good, and food efficiency of the diet containing pentadecanoic acid was equivalent to the control rats (fed by myristic acid). However, abnormalities in pathological examination were slightly observed on the rats fed by pentadecanoic acid.
