Two amino acids, one peptide bond. In this usage, X dipeptide (with X designating an amino acid) must be understood as di-X peptide. This nomenclature is continued by tripeptide (three amino acids, two peptide bonds), tetrapeptide, and so on; longer chains are called oligopeptide, polypeptide, protein.
These nerves carry instructions from the brain to every single part of your body. So if a bulging disc that causes lower back pain is pressing on a nerve that serves the stomach, for example, thereâs an excellent chance that the stomach will also experience pain and function at a diminished capacity.
