Metabolite Identification
Common NameDinophysistoxin 2
DescriptionDinophysistoxin 2 belongs to the class of organic compounds known as ketals. These are acetals derived from ketones by replacement of the oxo group by two hydrocarbyloxy groups R2C(OR)2 ( R not Hydrogen ). This term, once abandoned, has been reinstated as a subclass of acetals. Dinophysistoxin 2 has been detected, but not quantified in, mollusks. This could make dinophysistoxin 2 a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on Dinophysistoxin 2.
