1857 W. A. Miller Elements Chem. III. 628 Tyrosine forms long fibrous crystals, which are very sparingly soluble in cold water.

1873 C. H. Ralfe Outl. Physiol. Chem. 72 Tyrosin... Associated with leucin it has been obtained from all the glandular organs and secretions of the body.

1873 C. H. Ralfe Outl. Physiol. Chem. 72 On cooling, crystals of tyrosin will be deposited.

1897 T. C. Allbutt et al. Syst. Med. IV. 100 Tyrosin crystals were found in the urine.

1926 Jrnl. Biol. Chem. 70 140 Tyrosine is also deaminated during the fermentation.

1955 Sci. Amer. July 75/2 The six virus strains were analyzed for their content of three amino acids: tyrosine, tryptophan and phenylalanine.

1965 J. Lee & F. Knowles Animal Hormones v. 91 Basically, thyroid hormone consists of iodine conjugated with tyrosine.

1982 T. I. Diamondstone in T. M. Devlin Textbk. Biochem. xii. 614/2 Melanin is formed from tyrosine via l-dopa as intermediate; however, the enzyme that catalyzes the formation of l-dopa in this pathway is not tyrosine hydroxylase, but a copper-containing oxygenase known as tyrosinase.
