Notes:
Surfac-enhanced Raman spectra of L-tryptophanylglycine (L-Trp-Gly) and L-tryptophanylglycylglycine (L -Trp-Gly-Gly) adsorbed on a silver surface were obtained. More detailed investigations than in a previous study on the surface-enhanced Raman scattering from L-tryptophan (L- Trp) and glycyl-L-tryptophan (Gly-L-Trp) were also made. It was found that L-Trp and the above peptides adsorb on the silver surface via both the carboxylate (COO-) and the amino (NH2) groups. Interestingly, the nitrogen atom of the indole ring of L-Trp was found to bind to the surface only when L-Trp is the C-terminal residue.
