Common NameD-octopine
DescriptionD-octopine is a member of the amino acid derivative chemical class, specifically categorized as a cyclic imine. Its chemical structure features a unique arrangement derived from the condensation of l-arginine and pyruvate, facilitated by the enzyme octopine dehydrogenase (OcDH). This reaction, which occurs in the adductor muscle of the great scallop (Pecten maximus), produces D-octopine, NAD(+), and water, particularly during periods of intense muscular activity and subsequent recovery (PMID:22496288 ). The formation of D-octopine is closely linked to glycolytic pathways, where NADH generated from the oxidation of 3-phosphoglyceraldehyde is reoxidized during its synthesis (PMID:22496288 ). Notably, D-octopine has been identified as a potentially sensitive biomarker for assessing amino acid balance in birds, influenced by dietary amino acid patterns (PMID:39538238 ). Furthermore, in some scallops, D-octopine accumulation occurs during prolonged muscular exertion, while in others, its production peaks post-swimming, indicating its role in energy metabolism and recovery processes (PMID:22496288 ).
