Tyrosine (Tyr or Y[1]) or 4-hydroxyphenylalanine is an amino acid.

Tyrosine is one of the 20 standard amino acids used by cells to make proteins. It is a non-essential amino acid, meaning the body can make it. Its codons are UAC and UAU.

Tyrosine can be synthesized in the body from phenylalanine. It is also found in many high-protein food products such as chicken, turkey, fish, milk, yogurt, cottage cheese, cheese, peanuts, almonds, pumpkin seeds, sesame seeds, soy products, lima beans, avocados, bananas and eggs.[2]

It is called tyrosyl when referred to as a functional group or side chain.[3]
