Ketone bodies, acetyl-CoA, and glucose are three metabolites that result from the breakdown of the carbon skeleton of amino acids. Determine which of these metabolites are produced by ketogenic amino acids and which by glucogenic amino acids.
Which of the following molecules in the citric acid cycle do the carbon skeletons of glucogenic amino acids enter?
(i) α-ketoglutarate
(ii) succinyl-CoA,
(iii) oxaloacetate
(iv) fumarate
True or false: Certain amino acids can be both ketogenic and glucogenic. Provide an explanation for your answer.
What is/are the metabolic product/s generated from the carbon atoms of phenylalanine during its catabolism?
In the citric acid cycle, what metabolic substrates can be produced from the carbon atoms of aspartate?
During metabolism, which compounds are directly produced from the carbon atoms of the amino acid aspartate?
