Itâs not a major part of any starvation response. Once proteins are degraded, the amino acids may be used in anabolism to make new proteins, or may be catabolized to produce energy. Amino acid catabolism produces ammonia (NH3) and the carbon skeleton. Ammonia is toxic and has to be managed by the urea cycle.
Unlike fat and starch, the human body does not store excess amino acids for later useâthe amino acids must be in the food every day. The 10 amino acids that we can produce are alanine, asparagine, aspartic acid, cysteine, glutamic acid, glutamine, glycine, proline, serine and tyrosine.Tyrosine is produced from phenylalanine, so if the diet is deficient in phenylalanine, tyrosine will be required as well.he precise amino acid content, and the sequence of those amino acids, of a specific protein, is determined by the sequence of the bases in the gene that encodes that protein. The chemical properties of the amino acids of proteins determine the biological activity of the protein.
