Histidine amino acid molecule. Computer illustration showing the structure of a molecule of the amino acid histidine (C6.H9.N3.O2). Atoms are represented as spheres and are colour-coded: carbon (black), hydrogen (white), nitrogen (blue) and oxygen (red). This essential amino acid has many vital functions within the body and is involved in the synthesis of haemoglobin, tissue repair and the strengthening of the immune system. It is produced in very small amounts by the human body so it must predominantly be taken through the diet. | |
