Differences in fatty acid composition of various tissues of the marmoset monkey (Callithrix jacchus) after different lipid supplemented diets

1. The fatty acid composition of different muscles, organs and blood components of the marmoset monkey were examined after long-term feeding of several well defined lipid supplemented diets. 2. Similarities between the fatty acid composition of cardiac and skeletal muscles which persisted after all diets suggest that biopsy of skeletal muscle may have an important diagnostic value in this and other primate species. 3. The relationship between the dietary intake of individual fatty acids and their proportions in different tissues is both complex and variable. 4. However, the lipid metabolism of Callithrix jacchus recommends this small non-human primate as a most suitable species for the study of lipid nutrition.
