Please note that this figure is different than the one in your book and even the one that I put up on the board. It is however the most accurate figure that I can find. The important thing to remember is that all of these amino acids are catabolized into a metabolite that can be converted into a ketone body and that must eventually be converted into acetyl CoA. I will not ask you to match the exact amino acids with the exact catabolic product on any examination but you should know the ketogenic amino acids.
