And this group is now transferred onto the coenzyme A via the third step that is catalyzed by Dihydrolipol transacetilase e two. This is the enzyme that catalyzes the transfer of that activated acetyl group onto this molecule here, the coenzyme. Now, once this process takes place and this obtains so the coenzyme may obtain this structure, we form dihydrolipoamide. And this is not the same structure that we begin with here. Notice that in step three, we don't actually regenerate the lipo amide that we used in step two. Unlike in this case, where in step one we used TPP and we regenerated TPP here, we began with lipoamide and we ended up with dying hydro lipoamide.
