3 letter code: tyr 1 letter code: Y
Tyrosine is an aromatic amino acid. It is effectively hydroxy-phenylalanine.
Like all amino acids, it has an amino group (-NH2) - blue with 2 white balls - at one end, and a carboxylic acid group (-COOH) - grey, connected to red, and red and white - at the other end. Between these is the α- (alpha) carbon to which the 'R' group is attached.
In tyrosine, the 'R' group is rather bulky: a methyl group attached to a benzene ring carrying an -OH group.
Other informationTyrosine is involved in the production of the pigment melanin, which colours skin and hair.
