Well, once we form the cetil coenzyme A complex, it goes into the citric acid cycle and undergoes step one. And in step one, the ultimate goal is to combine the Cetal group of the cetil coenzyme A, the two carbon component, onto a four carbon component, a four carbon molecule found in the matrix of the mitochondria known as oxyloacetate. And this is the same oxyloacetate that we saw when we discussed Gluconeogenesis. So the four carbon molecule oxyloacetate is ultimately combined with this two carbon component, the CETL group of acetyl coenzyme A, to form a six carbon molecule 123456, known as citrate. Now, citrate is the conjugate base of citric acid and citric acid is an example of a tricarboxylic acid. And that's why the citric acid cycle is also sometimes known as the TCA cycle, tricarboxylic acid cycle.
