17.5: Protein Metabolism
Introduction
There are four protein metabolic pathways that will be covered in this section: Transamination -transfer of an amino group from one amino acid to another Deamination -removal of an amino group, normally from an amino acid. Gluconeogenesis -synthesis of glucose from a non-carbohydrate source. Protein Turnover/Degradation -liberation of amino acids from proteins.
Quick Overview of Protein Pathways, Cycles, Processes, or Reactions - names & definitions
A previous section described how proteins are synthesized. Thus, this section will focus on how proteins and amino acids are broken down. There are four protein metabolic pathways to remember:
-
Deamination
- removal of an amino group, normally from an amino acid.
-
Transamination
- transfer of an amino group from one amino acid to another
-
Gluconeogenesis
- synthesis of glucose from a non-carbohydrate source.
-
Protein Turnover/Degradation
- liberation of amino acids from proteins.
