Suggestion a catalytic interaction between homocysteine as a thiolic amino acid and vinylferrocene as an organometallic mediator at a control potential

New interaction between vinylferrocene (VF) and homocysteine (Hcy) was investigated in this work. At control potential, an electrocatalytic interaction occurs between Hcy and VF in aqueous buffer solution. Kinetic parameters such as electron transfer coefficient (?) and heterogeneous rate constant (kh) for Hcy were also determined using electrochemical approaches.
