甲状腺素Soduim盐是参与维持代谢稳态的甲状腺激素之一。合成并存储为甲状腺球蛋白（甲状腺滤泡胶体的主要蛋白质成分）的氨基酸残基。合成和分泌受垂体激素（TSH）调节。在周围组织中去碘化为活性代谢产物碘甲状腺素。 Thyroxine Soduim Salt is one of the thyroid hormones involved in the maintenance of metabolic homeostasis. Synthesized and stored as amino acid residues of thyroglobulin, the major protein component of the thyroid follicular colloid. Synthesis and secretion are regulated by the pituitary hormone (TSH). Deiodinated in peripheral tissues to the active metabolite, liothyronine.
