L-Thyronine
Thyronine (T0) is a de-iodinated form of thyroxine. Thyronine are a group of metabolites derived from thyroxine and triiodothyronine via the peripheral enzymatic removal of iodines from the thyroxine nucleus. Thyronine is the thyroxine nucleus devoid of its four iodine atoms. Thyronine (T0) has been identified in human urine. In 22 normal individuals urinary thyronine concentrations were found to range between 8-25 nmol‚ÅÑ24h (PMID: 479355). Thyronine is thought to be a byproduct of thyroxine metabolism and arises through the action of thyroxine deiodinases. Iodide is actively absorbed from the bloodstream and concentrated in the thyroid follicles. (If there is a deficiency of dietary iodine, the thyroid enlarges in an attempt to trap more iodine, resulting in goitre.) Via a reaction with the enzyme thyroperoxidase, iodine is covalently bound to tyrosine residues in the thyroglobulin molecules, forming monoiodotyrosine (MIT) and diiodotyrosine (DIT). Linking two moieties of DIT produces thyroxine. Combining one particle of MIT and one particle of DIT produces triiodothyronine.
