Glutamine amino acid molecule. Computer illustration showing the structure of a molecule of the amino acid glutamine (C5.H10.N2.O3). Atoms are represented as spheres and are colour-coded: carbon (black), hydrogen (white), nitrogen (blue) and oxygen (red). This non-essential (synthesised by the body) amino acid is used in protein synthesis and to support the production of the antioxidant glutathione. Although the body can produce it, immune system weaknesses and nerve problems can occur during times of high demand.
