So we have different aminotransferases, and two common examples are alanine and aspartate aminotransferases. So, as you might imagine, in this particular case, the beginning amino acid is alanine. In this case, it's aspartate. So in both cases, the alpha keto acid is alpha ketoglutrate. So we use this molecule to basically transfer this green alpha amino group onto the alpha ketoglutrate. Now, when we remove the alpha amino group, this green group from alanine, we basically form pyruvate.
