Metabolite Identification
Common NameBrevetoxin B2
DescriptionBrevetoxin B2, also known as BTXB2, belongs to the class of organic compounds known as brevetoxins and derivatives. These are a group of cyclic polyether compounds produced naturally by a species of dinoflagellate known as Karenia brevis. They contain a Pentaoxapentacycloheptacos- 23-en-7-one derivative (type a brevetoxin) or a pentaoxapentacyclotetracosa- 8,23-dien-7-one derivative (type b brevetoxin). Brevetoxin B2 is a very strong basic compound (based on its pKa). Outside of the human body, brevetoxin B2 has been detected, but not quantified in, mollusks. This could make brevetoxin B2 a potential biomarker for the consumption of these foods.
