So there are three different types of ketone bodies and this is one of them. So HMG coenzyme A is cleaved by an enzyme known as HMG coenzyme A. Liase we release this entire molecule here and we generate the aceto acetate molecule and notice that this is the base version of the acid. And so what that means is when we actually produce these ketone bodies, we will increase the acidity inside our body. And that can actually be dangerous, as we'll discuss in the future lecture when we'll talk about diabetes and ketone bodies. So this acetoacetate molecule is actually ketone body in itself and it will diffuse into the bloodstream. But some of these aceto acetate molecules will actually be converted to other ketone bodies in the liver.
