Metabolite Identification
Common Name6,7-Dihydro-7-hydroxyciguatoxin
Description6,7-Dihydro-7-hydroxyciguatoxin 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. 6,7-Dihydro-7-hydroxyciguatoxin is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, 6,7-dihydro-7-hydroxyciguatoxin has been detected, but not quantified in, fishes. This could make 6,7-dihydro-7-hydroxyciguatoxin a potential biomarker for the consumption of these foods.
