The occurrence of the human glycoconjugate C(2)-alpha-D-mannosylpyranosyl-L-tryptophan in marine ascidians.
[structure: see text] The C-glycoconjugate C(2)-alpha-D-mannosylpyranosyl-L-tryptophan (1), a metabolite known to be generated in humans through a novel posttranslational process, has been isolated from marine ascidians Leptoclinides dubius and Pharyngodictyon cauliflos and its N(alpha)-methyl derivative (2) from Ritterella rete.
