Myelin was found to contain five major glycoproteins with molecular weights of 120000, 95000, 88000, 43000 and 38000. Light myelin contained only 5-7% of the amount of these glycoproteins in whole myelin, whereas heavy myelin and the membrane fraction contained amounts nearly identical with whole myelin. Since all the major and minor glycoproteins, with the exception of 120000-mol-wt. glycoprotein, were detected only after treating the myelin membrane with neuraminidase, N-acetylneuraminic acid is a terminal sugar residue in these glycoproteins.
髓磷脂被发现含有五种主要糖蛋白，分子量分别为120000、95000、88000、43000和38000。轻髓磷脂所含这些糖蛋白的量仅为全髓磷脂的5 - 7%，而重髓磷脂和膜组分所含的量与全髓磷脂几乎相同。由于除了分子量为120000的糖蛋白外，所有主要和次要糖蛋白只有在用神经氨酸酶处理髓磷脂膜后才能检测到，因此N - 乙酰神经氨酸是这些糖蛋白中的末端糖残基。
