The marine sponge Spheciospongia vesparia produces vesparioside (1a), a diglycosylated glycosphingolipid which is the first example of a natural diglycosylceramide with a pentose sugar residue. The structure of vesparioside was mostly determined by extensive spectroscopic analysis but determination of the nature of the alkyl chains and elucidation of the absolute stereochemistry of the sugars and of
海海绵 Spheciospongia vesparia 产生 vesparioside (1a),一种双糖基化的鞘糖脂,它是第一个带有戊糖残基的天然双糖基神经酰胺的例子。vesparioside 的结构主要通过广泛的光谱分析确定,但确定烷基链的性质和阐明糖和神经酰胺的绝对立体化学需要化学降解。在这方面,这里首次采用了一种改进和简化的用于微尺度化学降解鞘糖脂的程序。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)
