title: Age-related changes of the branched-chain fatty acid concentration in rat skin surface lipid.
abstract: 1. Age-related change of the branched-chain fatty acid distribution in rat skin surface lipid was studied for 24 months. 2. The proportion of even carbon number iso-acid increased from infancy to month 5 and thereafter decreased with advancing age toward senescence. 3. Concentration of odd carbon number iso-acid depicted a similar shape of time course, but with a lesser magnitude and a peak value at month 1. 4. Anteiso- fatty acid reached the plateau level at month 5 and remained roughly constant through maturity to senescence.
