Abstract
- Ceramide composition and N-glycolylneuraminic acid content of gangliosides from gray and white matters and myelin of cerebrum and cerebellum were analyzed in eight species belonging to the suborder Odontoceti and two species to Mystacoceti. 2. The most characteristic feature was high contents of C20:0 (10-40%) and C24 species (5-40%). 3. Content of hydroxy fatty acid of C24 species was higher in cerebellum (5-20%) than cerebrum (0-3%). 4. Major component of long-chain base was dC18:1 (70-90%). 5. N-glycolylneuraminic acid was found in sperm whale, Dall's porpoise and killer whale (0.1-1.7%).
摘要
- 分析了齿鲸亚目8个物种以及须鲸亚目2个物种大脑和小脑的灰质、白质及髓磷脂中神经节苷脂的神经酰胺组成和N-乙酰神经氨酸含量。2. 最显著的特征是C20:0（10 - 40%）和C24种类（5 - 40%）的含量很高。3. C24种类的羟基脂肪酸在小脑（5 - 20%）中的含量高于大脑（0 - 3%）。4. 长链碱基的主要成分是dC18:1（70 - 90%）。5. 在抹香鲸、白腰鼠海豚和虎鲸中发现了N-乙酰神经氨酸（0.1 - 1.7%）。
