Take a look at the citric acid cycle. Look at the entry of acetyl CoA as the first step and oxaloacetate as the final. Determine each absorbed amino acid's probable point of entrance in the cycle and indicate the stoichiometric quantity of the citric acid cycle intermediate or starting material generated per oligopeptide molecule. If an amino acid has many entrance points into the cycle, you may choose any of them as long as stoichiometric connections are maintained.
