Although adipose tissue participates in lipid metabolism and reflects dietary patterns, little is known about the range of its fatty acid levels in free-living populations or what levels are abnormal. Tissue from the perirenal and buttock areas of 406 autopsied men, aged 15 to 44 years, was mainly composed of 6 fatty acids although others were present in very small percentage. Mean percentages of myristic and palmitoleic acids tended to be higher for whites than blacks for each age and site subgroup, whereas stearic acid was the opposite. Mean percentage of linoleic acid was higher for the younger age groups among whites than blacks in samples from both sites. Decrease in stearic acid and increase in oleic and palmitoleic acids in both races was associated with age, and linoleic acid was lower for the older than the younger age groups. Myristic, palmitic, and stearic acids were higher in perirenal tissue, whereas palmitoleic and oleic acids were higher in buttock tissue in both races.
