[ noun ] (biology,chemistry,biochemistry) tyrosine with two iodine atoms added
Used in print (Jacob Robbins et al., "The thyroid-stimulating...)In_addition , the iodoamino_acid formed in largest quantity in the intact thyroid is di-iodotyrosine . The mono - and di-iodotyrosine must be coupled to form tri-iodothyronine and thyroxine . The mechanism of this coupling has been studied in some detail with non-enzymatic systems in_vitro and can be simulated by certain di-iodotyrosine analogues ( Pitt-Rivers and James , 1958 ) . This de-iodinating enzyme is effective against mono - and di-iodotyrosine , but does not de-iodinate thyroxine or tri-iodothyronine . In the presence of a low iodine intake , thyroglobulin labelled in_vivo with * * f is found to contain more mono-iodotyrosine than normal , the amounts of di-iodotyrosine and iodothyronines being correspondingly reduced .
