Research Abstract	This study was focused on the supposition that Angel Wing (Pleurocybella porrigens) brain disorder was based on plural toxic causes. The refinement and the structural analysis of the peptidyl polysialic analogues having internal organs disorder characteristics and inflammatory nature showed that N-glycolyl neuraminic acid (NeuGc) indicating the antigenicity was specifically included in the glycoprotein of the Angel Wing. On the other hand, the structure of sphingoglycolipid A was determined and synthesized. Sphingoglycolipid A was presumed on impaired characteristics to the nervous system and intestinal epithelia.
