[ noun ] (biology,chemistry,biochemistry) tyrosine with one iodine atom added
Used in print (Jacob Robbins et al., "The thyroid-stimulating...)However , the formation of organically bound iodine , mainly mono-iodotyrosine , can be accomplished in cell-free systems . If tyrosine and a system generating hydrogen_peroxide are added to a cell-free homogenate of the thyroid , large quantities of free mono-iodotyrosine can be formed ( Alexander , 1959 ) . The mono - and di-iodotyrosine must be coupled to form tri-iodothyronine and thyroxine . 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 .
