Tissue proteins are continually being broken down and resynthesized, ingested amino acids being incorporated and those already present being eliminated. Certain amino acids necessary for growth and maintenance must be included in the diet, but others can be synthesized from non-protein precursors. Protein is formed from various combinations of ami
