The molecule is a tricarboxylic acid that is citric acid in which the pro-R carboxy group has been esterified with the primary hydroxy group of 2-hydroxy-1-{(2S)-1-[(2-hydroxyethyl)amino]-1-oxopropan-2-yl}-5-oxoproline. It is a siderophore isolated from bacteria closely associated or symbiotic with toxic, bloom-forming dinoflagellates. It has a role as a siderophore and a marine metabolite. It is a tertiary alcohol, a member of pyrrolidin-2-ones, a tricarboxylic acid, a carboxylic ester and a N-acyl hemiaminal. It derives from a citric acid. It is a conjugate acid of a vibrioferrin(3-).
