Prymnesin 1 is a chemical with the molecular formula C107H154Cl3NO44. See also Prymnesin-2
Prymnesins are a class of phycotoxins made by the alga Prymnesium parvum.[1][2] It is known to be toxic to fish, causing mass fish deaths around the world, including in Texas and England.
Structures
Prymnesins are formed of a large polyether polycyclic core with several conjugate double and triple bonds, chlorine and nitrogen heteroatoms and sugar moieties including L-xylose.[3] There are three forms of prymnesin known, prymnesin 1 and 2, differing in their glycosylation, and prymnesin B1[4] differing in backbone.
