Metabolic Pathways of Energy Use : Amino Acid and Protein Biosynthesis

Amino acids are required for protein biosynthesis.

All amino acids can be synthesized either directly or indirectly from intermediates of carbohydrate metabolism, particularly from the Krebs cycle.

 

 

Transamination or amination reactions:

Organic acids + an amine group = amino acid.

Not all organisms can do this.  Some require preformed amino acids.
