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.
This is in reference to the fact that this supplement was first discovered from casein, a cheese protein, in 1846. Tyrosine is found in a number of high protein food sources. This includes chicken, turkey, fish, peanuts, almonds, avocados, milk, cheese, yogurt, bananas, and soy products. Its chemical name also indicates that Tyrosine may be synthesized from Phenylalanine within the body.
