9Me)-h16:0], we developed a new method to purify this fungal glucosylceramide using ethanol precipitation and high-performance liquid chromatography. We also developed a new method to produce large amounts of a ceramide [d19:2(4E,8E,9Me)-h16:0] from this purified glucosylceramide using human glycoside hydrolase family 30 glucocerebrosidase (imiglucerase). These methods will be useful for elucidating
已知摄入植物和真菌葡萄糖神经酰胺可减少小鼠和人类的结肠癌发生和皮肤屏障损伤。但是,植物和真菌类神经酰胺在动物实验中的这种作用还没有被揭示,因为植物和真菌类神经酰胺的含量非常低,动物实验所需的大量神经酰胺很难获得。注意到真菌香菇 (Lentinula edodes) 富含葡萄糖神经酰胺 (4E,8E)-Nd-2'-hydroxypalmitoyl-1-O-β-d-glucopyranosyl-9-methyl-4,8-sphingadienine [Glc -d19:2(4E,8E,9Me)-h16:0],我们开发了一种使用乙醇沉淀和高效液相色谱纯化这种真菌葡萄糖神经酰胺的新方法。我们还开发了一种生产大量神经酰胺 [d19:2(4E,8E,9Me)-h16: 0] 使用人糖苷水解酶家族 30 葡糖脑苷脂酶(伊米苷酶)从这种纯化的葡萄糖神经酰胺中提取。这些方法将有助于阐明在动物实验中摄入真菌神经酰胺的生理功能。
