Lipid Fatty Acid Composition

The ovarian neutral lipid fatty acid composition was determined for 22 landlocked Atlantic salmon with gonadosomatic index ranging from 0.75 to 13.6. In fish with gonadosomatic index over 1.3, the proportions of 16:1 and 18:1 increased, while those of 20:5 (n – 3) and 22:6 (n – 3) decreased with increasing gonadosomatic index. The proportion of the other major neutral lipid fatty acid, 16:0, did not vary with gonadosomatic index. Analysis of selected samples did not reveal any relationship between gonadosomatic index and the proportions of the major phospholipid fatty acids, 22:6 (n – 3), 16:0, and 18:1.

Lipid Fatty Acid Composition

We have studied the influence of experimental hyperthyroidism in the rat on the synthesis of unsaturated fatty acids and on liver microsomal lipid fatty-acid composition. Tri-iodothyronine treatment (25 micrograms/100 g body weight) daily for 3 weeks caused no significant changes in delta 9 (stearate) desaturation but a 24% decrease in delta 6 (linoleate) desaturation. Much larger doses of tri-iodothyronine increased delta 9 desaturation. Liver microsomal fatty-acid composition in hyperthyroidism is altered with significantly increased proportions of stearate and arachidonate and decreased proportions of palmitate, palmitoleate, linoleate (C18:2) and eicosa-8,11,14-trienoate (C20:3). These changes, other than the decreases proportion of C20:3 fatty acid, which may be due to the diminished delta 6 desaturase activity, cannot be attributed to changes in fatty-acid desaturation. Most of these changes were also found to be due not simply to the decreased weight gain or the increased food intake of the hyperthyroid animals. Only the decreased C18:2 fatty-acid proportions could be mimicked by restricting food intake of control animals and none of the changes were prevented by restricting food intake of hyperthyroid animals. Thus most of the changes in microsomal lipid fatty-acid composition are likely to be due to a thyroid hormone effect on peripheral lipid mobilization or lipid degradation.
