And the oxalo acetate can be used in gluconeogenesis to generate sugar molecules, glucose. And so that's exactly why these five amino acids are labeled as glucogenic. So the strategy here is as follows. So, if we begin with glutamate, glutamate can simply be metabolized directly into alpha key gluterate. But if we have either one of these four amino acids shown here, they must first be metabolized into glutamate, and then glutrimate is in turn metabolized into alpha ketoglutrate. So this is the strategy that our cells employ.
