Base treatment of helical biliverdins with 2-chloroethyl side chains leads to intramolecular rearrangement to yield derivatives with extended conformations <89JAI525>. This work has been extended to include inter alia the syntheses of Neobiliverdin Ixd (26), a natural product from the ovaries of the sea snake Turbo cornutus, by reaction of (25) with base <95T2243,2255>. 

Among species which do have commercial value, the abalone, Haliotis gigantea, contains 23% protein, the wreath-shell. Turbo cornutus, 19% (Simidu et al., 1953). Both these species were from Japanese waters. 

Alginate lyase from Turbo cornutus acted on sodium alginate and resulted in a rapid decrease in viscosity and a gradual increase in reducing power of the substrate solution. The result of gel filtration of the reaction products indicated that uronic acid oligosaccharides were liberated as the final product. The fact that the enzyme attacked preferentially the D-mannuronate-rich moieties of the alginate molecule was demonstrated by an analysis with paper electrophoresis of the reaction products after acid treatment, which separated the uronic acid oligosaccharides from the uronic acid polysaccharides. 

The aminoalkylphosphorylcerebrosides in the muscle tissue of the marine snail. Turbo cornutus, have been characterized by g.c.-m.s. The major component was -0-[0 OX -methylaminoethylphosphonylj-D-galactosyn-ceramide while the minor component lacked the A -methyl group." ... 

A study has shown that phlorotannin mixtures, as well as the polymers dieckol (14), phlorofucofuroeckol A (15), and 8,8-bieckol (16) strongly inhibited digestive enzymes from the viscera of the herbivorous turban snail Turbo cornutus [57].
