[Comparative research on the cerebroside and sulfocerebroside content of the mammalian brain].
Data are presented on cerebroside and sulfocerebroside content of the brain for 31 mammalian species from 8 orders. The increase in concentration of both glycolipids in the brain of mammals in phylogenesis was demonstrated. Low levels of cerebrosides and sulfocerebrosides were found in the brain of lower mammals (Insectivora, Chiroptera) and high ones--in the brain of higher mammals (Carnivora, Primates). Irrespectively from taxonomic position and ecological factors, in the brain of all mammals investigated higher content of cerebrosides with hydroxy acids was found as compared to the content of cerebrosides with normal fatty acids. The ratio of these cerebrosides in the brain of terrestrial mammals is 2-3 times higher than in aquatic and semi-aquatic ones. The data obtained are discussed in relation to the development of the brain of mammals during their phylogenesis.
