Phenylalanine amino acid molecule. Computer illustration showing the structure of a molecule of the amino acid phenylalanine (C9.H11.NO2). Atoms are represented as spheres and are colour-coded: carbon (black), hydrogen (white), nitrogen (blue) and oxygen (red). Phenylalanine is an essential amino acid, which are unable to be produced by the body and must be sourced from the diet. It is a precursor for tyrosine, another amino acid involved in the production of the neurotransmitters norepinephrine (noradrenaline), dopamine, and epinephrine (adrenalin). | |
