So this will act as the reducing agent. And what will happen is electrons will be taken away from this acetyl group here. Or it's not actually in acetyl form just yet, but this purple region actually will abstract. Two electrons will give the electrons onto this component. And in the final step, those electrons that we give to the lipoamide will be taken away and given to the mad plus. So in the second step, we have another important coenzyme lipoic acid, actually a derivative of lipoic acid known as lipoamide.
