Metabolite Identification
Common NameBrevetoxin B4a
DescriptionBrevetoxin B4a, also known as BTXB4A, 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 B4a is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, brevetoxin B4A has been detected, but not quantified in, mollusks. This could make brevetoxin B4A a potential biomarker for the consumption of these foods.
