Metabolite Identification
Common NameLiothyronine
DescriptionLiothyronine, also known as T3 or liotironina, belongs to the class of organic compounds known as phenylalanine and derivatives. Phenylalanine and derivatives are compounds containing phenylalanine or a derivative thereof resulting from reaction of phenylalanine at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. Liothyronine is a drug which is used as replacement or supplemental therapy in patients with hypothyroidism of any etiology, except transient hypothyrodism during the recovery phase of subacute thyroiditis. Liothyronine is possibly soluble (in water) and a very strong basic compound (based on its pKa). Liothyronine exists in all living organisms, ranging from bacteria to humans. In cattle, liothyronine is involved in the metabolic pathway called thyroid hormone synthesis pathway. Liothyronine is a potentially toxic compound.

Enzymes

General function:
Involved in selenium binding
Specific function:
Responsible for the deiodination of T4 (3,5,3',5'-tetraiodothyronine) into RT3 (3,3',5'-triiodothyronine) and of T3 (3,5,3'-triiodothyronine) into T2 (3,3'-diiodothyronine). RT3 and T2 are inactive metabolites. May play a role in preventing premature exposure of developing fetal tissues to adult levels of thyroid hormones. Can regulate circulating fetal thyroid hormone concentrations throughout gestation. Essential role for regulation of thyroid hormone inactivation during embryological development.
