Module 6: Amino Acids and Proteins Obj. 5

Question 1

Deamination process, starting and ending substances

Answer 1

amino acid converted to its corresponding alpha-keto acid plus ammonia
Takes place in liver and renal tubular cells

ex. glutamine = glutamic acid + ammonia

Question 2

Transamination process, starting and ending substances

Answer 2

transfer of an amino group from an amino acid to an alpha-leto acid thereby creating a new amino acid and a new alpha-keto acid

Reaction catalyzed by aminotransferases and require pyridoxal-5-phosphate as the coenzyme

Question 3

2 primary enzymes involved in transamination reactions in the liver

Answer 3

aspartate aminotransferase (AST)
alanine aminotransferase (ALT)
