Quizplus · Accepted Answer

Isoleucine and tyrosine are both ketogenic and glucogenic amino acids, meaning they can be converted into both ketone bodies and glucose via different metabolic pathways. The other amino acids listed are either purely ketogenic (valine) or purely glucogenic (histidine, arginine) or both ketogenic and glucogenic but not listed (phenylalanine, tryptophan).
