Occurrence of ungulic acid in some epidermal tissues.
The lipids isolated from different animal tissues have been studied qualitatively, by TLC, for the occurrence of the ungulic acid fraction. This fraction was found in considerable amounts only in epidermal tissues and its keratinized derivatives. In the present study it was isolated from human keratinous epidermis, hair, and nails, pig bristles, wool, and feathers. The analytical results indicated that a lipid fraction from all of these sources contained ceramide, galactose, galactosamine, sulfate, and sialic acid in equimolar amounts, and that the fractions were similar to the ungulic acid isolated earlier from a horse's hoof.
