    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.

    Let's pull it all together what you learned about 'protein metabolism'
