Total lipid was extracted from chicken (Gallus domesticus) epidermis, leg scale, claws, feathers and preen glands and analyzed by quantitative thin-layer chromatography. All of the tissue lipids contained large proportions of wax diesters, triglycerides, and free sterols and variable proportions of phospholipids, steryl esters and free fatty acids. All of the keratinized tissues, but not the preen gland, contained ceramides, acylceramides and cholesteryl sulfate. Acylglucosylceramides were found only in full thickness epidermis. Glucosylsterols and acylglucosylsterols were found in the keratinized tissues, and may be of significance in the evolutionary history of the epidermal water barrier.
从鸡（家鸡）的表皮、腿鳞片、爪子、羽毛和尾脂腺中提取总脂质，并通过定量薄层色谱法进行分析。所有组织脂质都含有大量的蜡酯、甘油三酯和游离甾醇，以及不同比例的磷脂、甾醇酯和游离脂肪酸。所有角质化组织（但不包括尾脂腺）都含有神经酰胺、酰基神经酰胺和硫酸胆固醇酯。酰基葡萄糖神经酰胺仅在全层表皮中发现。葡萄糖基甾醇和酰基葡萄糖基甾醇存在于角质化组织中，可能在表皮水屏障的进化史上具有重要意义。
