The concentration and fatty acid composition of lipids from the sixth to thirty-second week of gestation has been measured in human fetal tissues. The data found show that the lipid concentration and fatty acid composition does not vary significantly during these stages of development. However, more palmitic acid and less linoleic acid is detected in fetal adipose tissue than in that of the mother and this relationship does not change in the immediate postpartum period. The results suggest that fetal lipid metabolism is well established early in gestation and that the concentration of lipids increases in proportion to the rate of growth of the fetal organs and cell structure.

Because brown adipose tissue lipids are the preferred substrate for thermogenesis during arousal from hibernation, the fatty acid composition of brown fat lipids was followed during cold acclimation and during a hibernation bout. In control golden hamsters (living at 22 degrees C), the fatty acid composition of the white adipose tissue closely resembled that of the food, but brown adipose tissue contained more animal-derived fatty acids. As an effect of acclimation to cold, the fatty acid composition of brown adipose tissue changed to resemble that of the food, and no marked differences between white and brown adipose tissue were then evident. During a hibernation bout, a major part of the fatty acids accumulated in brown fat during entry into hibernation consisted of "rare" acids, such as homo-gamma-linoleic acid. Homo-gamma-linoleic, together with eicosadienoic acid and lignoceric acid, was preferentially utilized during the early phase of arousal. During this phase, "bulk" fatty acids, such as linoleic acid, were spared, whereas in late arousal, linoleic acid was the preferred substrate. It was concluded that rare fatty acids are of quantitative significance in brown adipose tissue during hibernation and arousal.

1. Female rats were given throughout pregnancy and lactation a semi-synthetic diet, in which the fat was provided entirely by a soft margarine rich in linoleic acid (18:2ω6) or by mixture of butter and lard, and the influence on the fatty acid composition of fetal and pup brain and retinal phosphoglycerides was studied.2. The percentage of docosahexaenoic acid (22:6ω3) was much lower but that of docosapentaenoic acid (22:5ω6) was correspondingly higher in the brains of the day-22 fetuses and the 21-d-old pups from the margarine group compared with those from the group given the animal fats. Similar changes were noted in the synaptosomal and retinal phosphoglycerides, being most marked in the ethanolamine phosphoglycerides.3. The remaining pups from two groups were weaned on day 21 post partum on to the same stock diet that contained preformed 22:6ω3. After 9 weeks of this diet, the differences between the two groups in the fatty acid composition of the brain phosphoglycerides were barely discernible. The percentage of 22:5ω6 had decreased and had been replaced by 22:6ω3.4. It is concluded that the consequences of consuming a diet rich in linoleic acid and almost devoid of 22:6ω3 on brain fatty acid composition deserve consideration in man.
