How is t3 and t4 synthesized
Web20 jan. 2024 · Tetraiodothyronine (T4), the main hormone synthesized in the thyroid gland, is catalyzed to the Triiodothyronine (T3) by specific iodothyronine deiodinases ( 2 ). T3 acts as the principal TH mediating metabolic activity, via formation of complexes between T3 and nuclear thyroid hormone receptors alpha (TRα) and beta (TRβ). http://www.vivo.colostate.edu/hbooks/pathphys/endocrine/thyroid/synthesis.html

The effects of T4 in vivo are mediated via T3 (T4 is converted to T3 in target tissues). T3 is three to five times as active than T4. Thyroxine (3,5,3′,5′-tetraiodothyronine) is produced by follicular cells of the thyroid gland. It is pr…
Web3 nov. 2024 · T3 contains 3 iodine atoms and is created from the breakdown of T4. The breakdown of T4 is encouraged by the thyroid-stimulating hormone. T4 is synthesized from residues of the amino acid tyrosine, found in thyroglobulin (a protein created in the thyroid). It contains 4 iodine atoms and allows the body to better control the more active T3. WebSynthesis and Secretion of Thyroid Hormones.
