Influence of nicotinic acid or its isomers on direct electrochemistry of cytochrome c

Cytochrome c is a kind of electron transfer carrier in the living organisms. In recent years, many electrochemists have been interested in its electrochemical behaviour. In this letter are studied the promoting effects of nicotinic acid and its isomers, which are related to the electron transfer of cytochrome c in the respiratory chain. Hill and coworkers
