L-Thyroxine Chemical Properties,Uses,Production

Chemical Properties

Crystalline Solid

Uses

antihypercholesterimic, thyromimetic

Uses

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. The D-form has very little activity as a thyroi d hormone, but has been used to treat hyperlipidemia.

Definition

ChEBI: The L-enantiomer of thyroxine.
