Acylglucosylceramides of pig epidermis: structure determination.
The acylglucosylceramides of pig epidermis comprise 56% of the total glucosylceramides and 3.3% of the total epidermal lipid by weight. Contrary to an earlier report on this lipid, the amide-linked fatty acid is not a dihydroxypentatriacontadienoic acid; rather, the fatty acids are a series of long chain omega-hydroxy acids consisting of 58% saturates, 35% monoenes, and 7% dienes, with predomin...
متن کاملDetection of novel CYP11A1-derived secosteroids in the human epidermis and serum and pig adrenal gland
To investigate whether novel pathways of vitamin D3 (D3) and 7-dehydrocholesterol (7DHC) metabolism initiated by CYP11A1 and previously characterized in vitro, occur in vivo, we analyzed samples of human serum and epidermis, and pig adrenals for the presence of intermediates and products of these pathways. We extracted human epidermis from 13 individuals and sera from 13 individuals and analyze...
متن کاملGlucosylceramides of pig epidermis: structure determination.
Six series of glucosylceramides from pig epidermis have been identified, and their structures have been determined. The structural types identified are: 1, N-acylglucosylsphingosines (33%); 2, N-acylglucosylphytosphingosines (13%); 3, N-(omega-hydroxyacyl)-glucosylsphingosines (3%); 4, N-(alpha-hydroxyacyl)-glucosylphingosines (15%); 5, N-(alpha-hydroxyacyl)-glucosylsphingosines (16%); 6, N-(al...
متن کاملMucopolysaccharides in human epidermis.
In a previous publication on the Gram staining material of human epidermis we advanced the theory that keratohyalin contained a highly resistant mucopolysaccharide. In the course of normal keratinization this material was decomposed, while in parakeratotic and many other types of pathologic scales it was retained in the horny layer (1). The evidence presented was indirect: we found that the ext...
متن کاملLipid compositions of cells isolated from pig, human, and rat epidermis.
Epidermal slices from pig, human, and rat skin were treated with dilute buffered trypsin solution (0.005%, w/v), and suspensions of mixed basal and spinous cells were obtained in good yield. Total lipids accounted for approximately 8% of the pig, 10% of the human, and 20% of the rat epidermal cell (dry weight). Phospholipids in pig, human, and rat cells accounted for, respectively, 62%, 53%, an...
