title: The fatty acids of human sebaceous gland phosphatidylcholine.
abstract: The fatty acids of human sebaceous gland phosphatidylcholine were examined by gas chromatography and by analysis of the double bond positions in the C-16 and C-18 monoenes. Compared to phosphatidylcholine from other organs, sebaceous gland phosphatidylcholine was found to be deficient in essential fatty acids and poly-unsaturated fatty acids. The relatively large mono-unsaturated fatty acid fraction consisted predominantly of fatty acids with delta6- and delta8-unsaturation. Analysis indicates that the fatty acids of sebaceous gland phospholipids are predominantly of types synthesized in sebaceous glands.
