THE AMINO ACID COMPOSITION OF THE HORNY LAYER OF THE HUMAN SKIN

[摘要] The N, S, ash, lipoid content and amino acid composition of 3 different calluses and of scales derived from psoriasis, exfoliative dermatitis and disseminated neurodermatitis, were determined. All ash and lipid values and amino acid compositions of the calluses were within the same range. The amino acid composition of the investigated scales, as compared to the calluses, contained more S, cystine, methionine, tryptophan and aspartic acid and less glycine. The composition of the scales of different pathological origin was within the same range, indicating variations in the rate of the formation, but not in their amino acid structure.
