Alanine amino acid molecule. Computer illustration showing the structure of a molecule of the small non-essential genetically coded amino acid alanine (C3.H7.N.O2). Atoms are represented as spheres and are colour-coded: carbon (black), hydrogen (white), Nitrogen (blue), and Oxygen (red). Illustration. Alanine is synthesised by the body and constitutes a source of energy for muscles and the central nervous system (CNS), but also helps in the metabolism of sugars and organic acids.
