Metabolite Identification
Common Name52-Epiciguatoxin
Description52-Epiciguatoxin belongs to the class of organic compounds known as ciguatera toxins. These are lipid-soluble polyether compounds consisting of 13 to 14 rings fused by ether linkages into a most rigid ladder-like structure. 52-Epiciguatoxin is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, 52-epiciguatoxin has been detected, but not quantified in, fishes. This could make 52-epiciguatoxin a potential biomarker for the consumption of these foods.
