| Section2 = | Section3 = }} Yessotoxins are a group of lipophilic, sulfur bearing polyether toxins that are related to ciguatoxins. They are produced by a variety of dinoflagellates, most notably ''Lingulodinium polyedrum'' and ''Gonyaulax spinifera''. When the environmental conditions encourage the growth of YTX producing dinoflagellates, the toxin(s) bioaccumulate in edible tissues of bivalve molluscs, including mussels, scallops, and clams, thus allowing entry of YTX into the food chain. == History == The first YTX analog discovered, yessotoxin, was initially found in the scallop species ''Patinopecten yessoensis'' in the 1960s. Since then, numerous yessotoxin analogs have been isolated from shellfish and marine algae (including 45-hydroxyyessotoxin and carboxyyessotoxin).〔 Initially, scientists wrongly classified YTXs in the group of diarrhetic shellfish poisoning (DSP) toxins along the lines of okadaic acid and azaspiracids. These type of toxins can cause extreme gastrointestinal upset and accelerate cancer growth. Once scientists realized YTXs did not have the same toxicological mechanism of action as the other toxins (protein phosphatase inhibitors), they were given their own classification. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Yessotoxin」の詳細全文を読む スポンサード リンク
