Influence of Hair Growth Cycle on the Triglyceride Fatty Acid Composition of Mouse Epidermis.

Abstract

The fatty acid content of 2, 4, 12 and 22 day post plucking male and 2 and 4 day post plucking female epidermal triglycerides is quite similar. Oleic and linoleic acids are present in about equal amounts and represent some 70% of total fatty acid content whereas palmitic acid is some 18% of total fatty acid level. Triglycerides of post plucking days 12 and 22 of female epidermis have more oleic and much less linoleic acids than do the triglycerides of the other samples. At the time of most rapid cell division in the epidermis (2–4 days post plucking) there appears to be no significant change in triglyceride fatty acid composition.
