Raman vibrational spectra were obtained from crystalline amino acids and acid molecules adsorbed at the surfaces of silver electrodes in aqueous solutions. Results revealed that aromatic acids such as phenylalanine adsorbed via their aromatic ring while bases such as alanine were coordinated by their amine functional groups. Sulphur containing acids (cysteine and cystine) were found to bond through their sulphur groups. In all cases, adsorption increased towards the point of zero charge of silver, as would be expected for uncharged species. Similar experiments carried out on α-amylase solutions showed that the enzyme molecule changes its coordination to the silver surface as a function of electrode potential, indicating that C-S, C-N, and aromatic ring functional groups are all present on the outer surface of the enzyme structure. |
