Homarine, a Common Metabolite in Edible Mediterranean Molluscs: Occurrence, Spectral Data and Revision of a Related Structure

Abstract

Abstract Homarine was isolated from nine edible species of marine molluscs belonging to classes Gastropoda, Bivalvia, and Cephalopoda. A thorough chromatographic, NMR and MS study provided evidence that homarine is a common and abundant metabolite of all these species. This study casts doubt on a previous assertion that 1,1′-dimethyl-[2,2′]-bipyridinium is a metabolite of the Bivalve Callista chione.
