has role has role is conjugate acid of is tautomer of 3,3',5-triiodo-L-thyronine CHEBI:11702 CHEBI:11701 CHEBI:9722 An iodothyronine compound having iodo substituents at the 3-, 3'- and 5-positions. Although some is produced in the thyroid, most of the 3,3',5-triiodo-<small>L</small>-thyronine in the body is generated by mono-deiodination of <small>L</small>-thyroxine in the peripheral tissues. Its metabolic activity is about 3 to 5 times that of <small>L</small>-thyroxine. The sodium salt is used in the treatment of hypothyroidism.
