“ Ketones are a completely different set of chemicals than amino acids”
No, not at all.
Ketones are a component of several aminos, notably leucine, lysine, and others like phenylalanine, tyrosine, tryptophan, and isoleucine, all of which are classified as ketogenic because their carbon skeletons can be converted into ketone bodies.
Sigh. Just because some amino acids have ketone groups doesn’t mean they should be conflated.
