Metabolite Identification
Common NamePacific Ciguatoxin 4A
DescriptionPacific Ciguatoxin 4A, also known as ciguatoxin 4A or p-CTX 4A, 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. Pacific Ciguatoxin 4A is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, pacific ciguatoxin 4A has been detected, but not quantified in, fishes. This could make pacific ciguatoxin 4A a potential biomarker for the consumption of these foods. Pacific Ciguatoxin 4A is a potentially toxic compound.
