Lipids extracted from the kidneys of adults with renal cell carcinoma or infection after careful dissection of lesions and from organs showing minimal alterations were saponified and the fatty acids converted to the methyl esters. Gas chromatographic criteria were applied to the esters as such and to hydrogenated aliquots, and the relative percentages of the component acids were ascertained. The various lipid classes were well represented in the total fatty acid mixtures. The unsaturated acids ranged higher than the saturated homologs. Comparisons of the fatty acids were carried out on the basis of age, sex, kidney position, mode of ascquisition (surgery and autopsy), and pathology. Several small but statistically significant differences were discerned according to the categories but with few exceptions, these involved acids occurring at low levels and with wide variance.
