Biological roles: 1. Amino acids can be metabolized to produce energy. This is especially. important during fasting, when the breakdown of muscle protein is a major. source of energy and biosynthetic precursors. 2. Some amino acids act as neurotransmitters, and some act as starting.
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.
