Ectyoceramide (1a), a unique monoglycosylceramide with a galactose in the furanose form, was isolated from Ectyoplasia ferox, and its structure was determined by NMR spectroscopy, multiple tandem mass spectrometry, and chemical degradation. Ectyoceramide is the first example of a monohexofuranosylceramide and, more generally, the first natural glycosphingolipid with its first sugar in the furanose
Ectyoceramide (1a) 是一种独特的单糖基神经酰胺,含有呋喃糖形式的半乳糖,是从 Ectyoplasia ferox 中分离出来的,其结构由核磁共振光谱、多重串联质谱和化学降解确定。胞外神经酰胺是单己呋喃糖基神经酰胺的第一个例子,更一般地说,是第一个含有呋喃糖形式的糖的天然鞘糖脂。(Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)
