Advanced Biochem Exam III: Amino Acid Metabolism Questions With Complete Solutions

synthesizes argininosuccinate using ATP and aspartate Argininosuccinate synthetase transfers a carbamoyl group to ornithine to form citruline Ornithine transcarbamoylase Argininosuccinate lyase non-hydrolytic cleavage of argininoosuccinate Arginase (hydrolase of arginine) - urea and ornathine ALT/ALAT alanine aminotransferase pyruvate --ALAT-- alanine AST/ASAT aspartate aminotransferase oxaloacetate --ASAT-- aspartate Ribose 5-phosphate (PPP) is the source of what AA? histidine (tbh, might not even need to know) 3-PG (glycolysis) is the source of what AAs? CGS serine, and then glycine and cysteine (pretty similar structures) pyruvate (glycolysis) is the source of what AAs? the branched AAs (just carbon chains as sidechains): alanine, valine, leucine, and isoleucine PEP (glycolysis) is the source of what AAs? aromatic AAs: tryptophan, phenylalanine, tyrosine All AAs are made from intermediates in glycolysis, the citric acid cycle, or the pentose phosphate pathway. What is(are) the source(s) of: -histidine -serine, glycine, and cysteine -branched AAs (just carbon chains as sidechains): alanine, valine, leucine, and isoleucine -aromatic AAs: tryptophan, phenylalanine, tyrosine -glutamate, glutamine, proline, arginine -aspartate, asparagine, methionine, threonine, lysine
