Candida lipolytica yeast was grown batchwise on glucose medium. Cerebrosides were isolated from the sphingolipid fraction of total lipids using column chromatography and separated into two compounds by high-performance thin-layer chromatography. Glucose was detected as the sole sugar constituent in cerebrosides. The fatty acid composition of cerebrosides was characterised by a predominance of saturated fatty acids and by a high proportion of fatty acids with 16 carbon atoms. The dominant fatty acid was h16:0. The principal long-chain base components of both cerebroside species were trihydroxy bases, 18- and 20-phytosphinosine. The unique characteristic of cerebrosides was the presence of a high proportion of sphingosine (one-fourth of the total long-chain bases), which is a common characteristic of mammalian sphingolipids and rarely occurs in yeast cerebrosides. The ceramide moiety profile of cerebrosides is similar to that of epidermal ceramides, which implies a possibility for their application in care cosmetics.
解脂耶氏酵母在葡萄糖培养基上分批培养。使用柱色谱法从总脂质的鞘脂部分中分离出脑苷脂,并通过高效薄层色谱法将其分离为两种化合物。检测到葡萄糖是脑苷脂中唯一的糖类成分。脑苷脂的脂肪酸组成特点是饱和脂肪酸占主导,且含有高比例的16个碳原子的脂肪酸。主要脂肪酸为h16:0。两种脑苷脂种类的主要长链碱基成分都是三羟基碱基、18 - 和20 - 植物鞘氨醇。脑苷脂的独特特征是存在高比例的鞘氨醇(占总长链碱基的四分之一),这是哺乳动物鞘脂的共同特征,在酵母脑苷脂中很少出现。脑苷脂的神经酰胺部分谱与表皮神经酰胺相似,这意味着它们有可能应用于护理化妆品中。
