Metabolite Identification
Common NameBrevetoxin B4b
DescriptionBrevetoxin B4b, also known as BTXB4B, 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 B4b is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, brevetoxin B4B has been detected, but not quantified in, mollusks. This could make brevetoxin B4B a potential biomarker for the consumption of these foods.
