Question
This amino acid can be used to mimic phosphorylated serine or threonine. For 10 points each:
[10h] Name this amino acid whose side chain consists of a carboxyl group and an additional carbon, making it one carbon shorter than the chemically similar glutamate. It is abbreviated D.
ANSWER: aspartate [or aspartic acid or Asp]
[10e] Aspartate reacts with citrulline in the third step of the biochemical pathway that generates this namesake nitrogenous waste compound found in urine.
ANSWER: urea [or carbamide]
[10m] Urea is produced from this molecule, which is turned into its ion by glutamate dehydrogenase. Two units of this molecule react with carbon dioxide in the overall reaction of the urea cycle.
ANSWER: ammonia [or NH3 (“N-H-3”); prompt on ammonium or NH4+ (“N-H-4-plus”) by asking “give the non-ionic form”]
