octopinen.

Brit.

/ˈɒktəpiːn/,

/ˈɒktəpɪn/, U.S.

/ˈɑktəˌpin/

Forms: 1900s– octopin, 1900s– octopine.

Origin: A borrowing from German, combined with English elements. Etymons: octopus n., -ine suffix⁵, German Oktopin.

Etymology: < octopus n. (see note at that entry) + -ine suffix⁵, after German Oktopin (K. Morizawa 1927, in Acta Schol. Med. Univ. Imperialis Kioto 9 290), so called on account of the compound being first found in octopus muscle.

Biochemistry.

An amino acid of the opine group, C₉H₁₈N₄O₄, found in the tissues of some cephalopods and lamellibranch molluscs and also synthesized by plant cells infected by certain strains of the crown gall pathogen Agrobacterium tumefaciens. Cf. nopaline n.
