Iodothyronines
Web14 jul. 2005 · All iodothyronines also show significant abundances of the iodide anion in their tandem mass spectra, which represents an attractive target for multiple reaction monitoring (MRM) analysis, given that iodothyronines are the only iodine bearing endogenous molecules. WebWe have studied the kinetics of 3 iodothyronines, 3,3'-diiodothyronine (T2), 3',5'-T2, and 3'-monoiodothyronine (T1), in groups of young adult male rats maintained under normal steady state physiological conditions. We have also performed a comparative analysis of these results, combined with corres …

WebTwo major iodothyronines, thyroxine (3,5,3′,5′-tetraiodothyronine or T4) and 3,5,3′-triiodothyronine (T3) are synthesized in the thyroid gland (Fig. 1 ). T3, the primary active form of thyroid hormone (TH), is also produced by local conversion of T4 to T3 by deiodination in some peripheral organs. The major actions of T3 are mediated by a ... Web1 mei 2002 · The abilities of various iodothyronines and iodotyrosines to displace the binding of rT 3 to its specific antibody were tested in four to five different concentrations. Cross-reaction of the rT 3 antibody was minimal with all compounds tested. The highest relative cross-reactivity was found for 3,3′-T 2 (1.0%). l-T 3 and d-T 3 showed values of …
