Booij M and ten Bosch JJ (1982) A fluorescent compound in bovine dental enamel matrix compared with synthetic dityrosine. Arch Oral Biol. 27: p. 417-21

	Dityrosine is a substance frequently found in structural proteins. Emission and excitation fluorescence spectra, absorption spectra, thin layer and molecular weight chromatography showed that the fluorescing enamel material isolated strongly resembled dityrosine and had at least an o,o-diphenyl bonding.
