Abstract
Serial samples were taken at regular intervals through the skin and subcutaneous adipose tissue of pigs and the lipid and fatty acid composition of each was determined. The triglycerides from the region immediately beneath the skin contained a much higher proportion of oleic acid and correspondingly less of the other fatty acids than did the triglycerides from the remainder of the tissue; there was a similar but less marked increase in the proportion of oleic acid in the triglycerides from the innermost sections of adipose tissue. There was a distinct discontinuity in the fatty acid composition at the line of connective tissue between the inner and outer layers of adipose tissue. The chemical changes were correlated with the morphological appearance of the tissue by histological examination.
