B a b u r a o +

Lipids extracted from the scalp hair of Caucasian boys, teenagers and adults and Black Teenagers of a boarding school, were saponified and the p u p s compared with respect to the total fatty acids by multiple discriminant analysis.ThelipidyieldsfromBlackrangedhigherthanthosefromCaucasians. Among the Caucasians, differences based on age were not significant. The total acids of hair lipids from Blacks differed significantly as comparedtothoseofthe Whitepups,atrendalsosupported byanalysesofacids in lipid classes of men 24-70 years of age. Hair from the latter was pooled according to race and scalp condition (balding and non-balding). With the latter 4 adult categories, acids of the mono-, di-and tri-acylglycerols and the free fatty acids were ascertained and compared, both on the basis of the overallacidsas wellasintermsoftheprominentsaturatedandunsaturatedhomologs. Racial differences were encountered in the fatty acids, the saturated acids distinguishing the free fatty acids and triacylglycerols and the unsaturated, the mono-and di-acylglycemls. For each category, the ratios of free fatty acids to triacylglycerols were not significant in contrast to the component acids as such. As based on theacids,significant differences alsooccurred with scalp condition in the respective racial groupings.
