Fatty acids of the alkane diol diesters of vernix caseosa

The fatty acid monoenes esterified to the alkane diol diesters of vernix caseosa lipid form two patterns of homologues starting from either C₁₆Δ9 or C₁₆Δ6 and adding (or subtracting) an integral number of C₂ units at the carboxyl group. Although components of the Δ6 pattern are the predominant monoenes of sebaceous gland ester lipid classes, for these diol diesters Δ9 pattern components are preferentially used.
