title: Diester waxes from skin lipids of the feet of biotin depleted and biotin supplemented turkey poults.
abstract: The neutral lipids of the skin from the feet of turkey poults fed a biotin supplemented or a biotin deficient diet consist mainly of triacyglycerols, and of mono- and diester waxes. Diester waxes from both groups were characterized as fatty acid esters of erythro-2,3-alkanediols. A comparison between fatty acid composition of the two groups, however, revealed the following significant differences. Biotin deficient birds showed a fairly high concentration of very long chain fatty acids (C36-C40) which were completely absent in biotin supplemented birds. Further, almost one-third of the fatty acids of diester waxes in biotin deficient birds were unsaturated while those from biotin supplemented birds were predominantly (96%) saturated.
