A comparison of the ganglioside distributions of fat tissues in various animals by two-dimensional thin layer
Abstract:
The ganglioside distributions of various fat tissues from human, rabbit, rat, mouse, chicken and frog were compared with pig adipose gangliosides by two-dimensional thin layer chromatography. It was found that there is a remarkable species variation in ganglioside distribution, especially in the composition and relative concentration of complex gangliosides. Differing from pig adipose tissues, those of human, rabbit, rat, mouse, chicken, but not frog, contained GM3 as a most abundant ganglioside. The data for human, rabbit and chicken indicated a simple distribution of only NeuAc-type gangliosides, while those for rat and mouse indicated a rather complicated pattern containing both NeuAc- and NeuGc-type gangliosides. The ganglioside pattern of the frog fat body differed markedly from those of mammalian fat tissues because of the presence of three different, unusual monosialosylgangliosides as major components. In other respects, a substantial amount of disialosylgangliosides was commonly found in all animal fat tissues.
