Two glycosphingolipids named soya-cerebrosides I and II were isolated from soybean, the seeds of Glycine max MERRILL (Leguminosae), and their chemical structures have been elucidated on the basis of physicochemical evidence and several chemical degradation reactions. By using a newly constructed liquid membrane-type apparatus (W-08) for measurement of ion-transport and ion-binding activities and by employing a method using human erythrocyte membranes for measurement of ion-permeability, it has been found that soya-cerebroside II exhibits ionophoretic activity for Ca2+ion.
从大豆(豆科)的种子大豆中分离出两种鞘糖脂,称为大豆脑苷脂 I 和 II,它们的化学结构已根据物理化学证据和几种化学降解反应得到阐明。通过使用新构建的液膜型装置(W-08)测量离子传输和离子结合活性,并采用使用人红细胞膜的方法测量离子渗透性,发现大豆脑苷脂II 对 Ca2+ 离子表现出离子电渗活性。
