The class of pigments are derivatives of the amino acid tyrosine.

Most are derived from the amino acid tyrosine.

The phosphate group is attached to the amino acid tyrosine on the protein.

More specifically it is formed by the decarboxylation of the amino acid tyrosine.

The fourth aromatic amino acid tyrosine can be synthesized from phenylalanine.

Melanin is a derivative of the amino acid tyrosine.

In animals melanin pigments are derivatives of the amino acid tyrosine.

Instead, the animals may synthesize the pigments from precursors such as the amino acid tyrosine.

And the amino acid tyrosine, a recent scientific report shows, can buffer the mental and physical effects of extreme stress.

It's produced as the amino acid tyrosine is converted into Melanin, which is found in the skin, hair, and eyes.
