Which amino acid can be considered to be both glucogenic and ketogenic?

Question

Quizplus · Accepted Answer

Threonine and isoleucine are both glucogenic and ketogenic amino acids. Glucogenic amino acids can be converted into glucose through gluconeogenesis, while ketogenic amino acids can be converted into ketone bodies. Threonine can form both pyruvate and acetyl-CoA, which can enter the Krebs cycle and ultimately lead to glucose production, as well as ketone body production. Isoleucine can be converted into both acetyl-CoA and succinyl-CoA, which have the same potential fate as threonine. Both of these amino acids have carbon skeletons that can be used for both energy production and glucose synthesis.
