Abstract
The distribution of cyclic betaines were examined comparatively in several organs of 10 species of fish. The distribution of homarine depended on the organs and fish: high levels in gonads, and medium levels in digestive contents and digestive organs were found in Clupeidae and Engraulidae. Homarine was also present in undetected or small amounts in the remaining five species belonging to Plecoglossidae, Scomberesocidae, Carangidae, Sciaenidae and Monacanthidae. Trigonelline and N-methyl isonicotinic acid—isomers of homarine—were scarcely found. Homarine content in fish was not closely related to their food.
