[Effect of acute stress on the fatty acid composition of lipids of adrenal and heart mitochondria in rabbits].
A comparative study of changes in the fatty acid composition of rabbit heart and adrenal mitochondria was carried out after acute (1h) immobilization stress. In heart mitochondria the stress induced a decrease in the content of capric, lauric, myristic and pentadecanic acids. A statistically significant reduction of the amount of heptadecanoic, linoleic, arachidonic acids and an increase in the level of palmitic acid was noted in adrenal mitochondria. The acute stress resulted in differently directed shifts in the saturation of fatty acids. An elevation of the sum of unsaturated fatty acids was observed in the heart, and a decrease was detected in the adrenal glands. The above shifts in the fatty acid composition of adrenal and heart mitochondria provide evidence for different directions of lipid metabolism in these organs following stress.
