Four compounds within citric acid cycle that the carbon skeletons of the glucogenic amino acid enter has to be identified. Concept introduction: The citric acid cycle includes a series of oxidation-reduction reactions in mitochondria that results in the oxidation of an acetyl group to two molecules of carbon dioxide and reduce the coenzymes that are reoxidized through the electron transport chain, linked to the formation of ATP Amino acids that are converted to a c e t o a c e t y l − C o A or a c e t y l − C o A then enter the ketogenesis pathway are called ketogenic amino acids. The amino acids that proceed by way of oxaloacetate to gluconeogenesis pathway are called glucogenic amino acids.
