penicillamine–glutathione mixed disulfide with their two amino groups protonated. The rate and equilibrium constants for the first step are much larger than those for the second step, indicating a small tendency for penicillamine to form its symmetrical disulfide by thiol/disulfideexchangereactions. This and the smaller reducing power of penicillamine as compared to glutathione are attributed to steric
