White crstals or crystalline powder. Freely soluble in formic acid, very slightlysoluble in water,practically insoluble in ethanol and in ether. Dissolve in dilute hydrochloric acid and in dilute nitric acid. Aside from being a proteinogenic amino acid, tyrosine has a special role by virtue of the phenol functionality.

Phosphorylation of the hydroxyl group changes the activity of the target protein.
