This study extends our previous work (Raclot, T., and R. Groscolas. 1993. J. Lipid Res. 34: 1515-1526) which demonstrated that in the fed state fatty acids are selectively released from white adipocytes in vitro. It aims at determining whether such selectivity operates in vivo during energy depletion and has physiological relevance. This question was examined in rats by simultaneously measuring...

This paper focused on analysis of fatty acids of erythrocytes and blood plasma in patients with multiple organ dysfunction syndrome. For the study, fatty acids ethyl esters, obtained during sample preparation from blood plasma and erythrocytes, were analyzed by capillary gas-liquid chromatography. Statistical analysis was performed using the Mann-Whitney U test (p<0.05). The conducted research ...

In order to understand feeding ecology, habitat use and migration of coral reef fish, fatty acid composition was examined in damselfish species Abudefduf bengalensis and A. sexfasciatus collected in the Malaysian South China Sea. Proportions of saturated fatty acids (SAFA) ranged from 49.5% to 74.2%, with the highest proportions in fatty acids, the second highest was monounsaturated fatty acids...

The nutritional image of bovine milk fat has suffered for years because of the association of saturated fatty acids and coronary heart disease. Thus the alteration of fatty acid composition has been a long-term strategy. Forages, even though containing a relatively low level of lipids, are the cheapest and often the major source of beneficial unsaturated fatty acids in ruminant diets. Recent pr...

This study was conducted to find the effects of fruit ripening and extraction method on the quantity and quality of the Koroneiki olive oil. The oil samples extracted in six ripening stages were used for further quality analysis. Quality assessment of the oil was conducted according to the standard methods and the composition of fatty acids was measured by gas chromatography. The results showed...

Ruminant milk fat is of unique composition among terrestrial mammals, due to its great diversity of component fatty acids. The diversity arises from the eVects of ruminal biohydrogenation on dietary unsaturated fatty acids and the range of fatty acids synthesized de novo in the mammary gland. Forty to sixty per cent of milk fatty acids are long-chain (predominantly C18) fatty acids derived from...

The effect of free cholesterol on the fatty acid composition and growth of rat fetal enterocytes was investigated in the absence and presence of 10% (v/v) fetal calf serum. Cholesterol caused a significant reduction of cell number after 6 and 12 h in culture. The fatty acid composition of enterocytes cultured in the presence of serum was also changed by the presence of 20 microM cholesterol. Th...
