Tyrosine (Tyr or Y) or 4-hydroxyphenylalanine is one of the 22 amino acids that are used by cells to synthesize proteins. It is a non-essential amino acid with a polar side group. Its codons are UAC and UAU.
Tyrosine is the amino acid that is specified by the codon UAU. The tRNA attaches to the mRNA in the ribosome and lines up tyrosine right next to the waiting methionine. A peptide bond forms between the two amino acids. Then, the first tRNA leaves everyone else behind and floats off to find more work to do.
