title: Dinoflagellate sterols I: Sterol c omposition of the dinoflagellates of Gonyaulax species.
abstract: The sterol composition of five species of dinoflagellates of the family Gonyaulacaeae (Div. Pyrrhophyta) were examined. All the five species (Gonyaulax acatenella, G. tamarensis, G. catennela, G. washing-tonesis, and G. polyedra) were found to contain 4 alpha-23,24(R)-trimethyl-5 alpha-cholest-22-en-3 -ol (dinosterol) and cholesterol as major sterols.
