In the adductor muscle of the scallop, Patinopecten yessoensis, two acidic amino acids were detected and isolated by ion exchange chromatography. One, obtained as needles, was identified as meso-α-iminodipropionic acid (I), which has recently been isolated from the muscle of the squid Todarodes pacificas. The other compound, obtained as prisms, was inferred to be D-α-iminopro-pioacetic acid (II) by elemental analysis and mass, NMR, ORD, and IR spectrometries; this was confirmed by comparison with data from an authentic specimen. In the liquid chromatography the peak of II appeared between cysteic acid and taurine, overlapping practically with that of I. It is very interesting to note that both I and II have a D-alanine moiety in the molecule, as do octopine and lysopine.
