Gangliosides in Fish Brain
Gangliosides are characteristic components of plasma membranes of the nervous cells. The complexity of ganglioside molecule determines the wide range of its variability, as all the components may vary due to the systematic position of species, the age of animals and the environmental factors, the organ specificity of composition being pronounced as well. Comparative biochemical studies are of importance for better understanding of evolutionary interrelationships of various animal groups and may throw light on functional roles of the substances studied. Progressive development of the central nervous system is characteristic of the process of phylogenetic development of vertebrates. In this connection brain appears to be interesting object especially taking into account ganglioside localization. In our studies of vertebrate brain gangliosides, the most detailed study was done on fish brain. The fishes are extremely numerous group diverse in their habitats, mode of life and level of development of the nervous system.
