Abstract
Homocysteine differs from cysteine in electrochemical behaviour due to slig ht differences in hydrophobicity and in structure of their complexes with m etals. This shows in adsorptivity, in anodic reactions with mercury, in cat alytic reductions of oxygen mediated by mercurous thiolates and of thiol-co balt(II) complexes, but most markedly in catalytic evolution of hydrogen fr om solutions containing cobalt ions.
