8.2.5.3 Cysteine
Electrochemical reduction of cystin to cysteine
is used in many countries, including the USA,
Japan, China and some European countries
(
Eq. 8.10
). Since separation of cysteine from
cystin is quite difficult, the electrolysis has to be
continued until all the starting cysteine has
been completely consumed. This means that at
the final stage of the electrolysis electricity is
consumed mainly for the reduction of protons
to evolve hydrogen gas, resulting in a decrease
in current efficiency, which is a problem that
has still to be overcome.
