Abstract
1.1. The chemical composition of coelacanth brain was studied and compared with some other species of bony fishes.2.2. Almost all lipid classes generally seen in vertebrate brains were detected: 22:1 and 22h:1 acids were abundant in cerebroside and 24:1 acid in ganglioside. The hydroxy fatty acid content of cerebroside was high.3.3. The myelin protein composition was unusual in that a 28,000-dalton protein was a major component.4.4. 2′,3′-Cyclic nucleotide 3′-phosphodiesterase was 10 times more active than in the other bony fishes.5.5. The present data suggest that molecular construction of coelacanth myelin is more advanced than that of the other bony fishes.
