| Abstract: | The total lipids from different regions of 6 dolphin brains were extracted and separated into individual fractions. The highest concentration of cerebrosides was found in the cerebral myelin and in the pons, the highest amount of lecithines in the cerebral cortex. After saponification of all fractions, the fatty acid composition was analysed by gas chromatography. The brain regions showed significant differences in relation to their origin. In comparison to the human brain, the brain of the dolphin contains more lipids due to the higher concentration of glycerophosphatides, whereas the contents of sphingolipids are identical in both species. |
