(-)-Tiroxina

Descripción:

(-)-Tiroxina, también conocido como L-tiroxina o T4, es una hormona producida por la glándula tiroides que juega un papel crucial en la regulación del metabolismo, el crecimiento y el desarrollo en el cuerpo. Es un derivado tetraiodado del aminoácido tirosina, caracterizado por la presencia de cuatro átomos de yodo en su estructura. La fórmula química de (-)-Tiroxina es C15H11I4N0, y tiene un peso molecular de aproximadamente 776.87 g/mol. Este compuesto se encuentra típicamente como un polvo cristalino blanco a blanco amarillento y es soluble en agua y alcohol, pero menos soluble en disolventes orgánicos. (-)-Tiroxina funciona al unirse a los receptores de hormonas tiroideas, influyendo en la expresión génica y los procesos metabólicos. Se utiliza comúnmente en entornos clínicos para tratar el hipotiroidismo y otros trastornos relacionados con la tiroides. Su actividad se monitorea de cerca, ya que tanto la deficiencia como el exceso pueden llevar a problemas de salud significativos. El número CAS 51-48-9 identifica de manera única este compuesto en bases de datos químicas, facilitando la investigación y el cumplimiento normativo.

Thyroxine (100% pure T4 reference standard (free of T3))

CAS: 51-48-9

Applications Thyroxine 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. The D-form has very little activity as a thyroid hormone, but has been used to treat hyperlipidemia.

Levothyroxine

CAS: 51-48-9

Levothyroxine is a thyroid hormone that is used to treat hypothyroidism. It is taken in tablet form, usually once per day. Levothyroxine therapy can be started with a low dose and increased gradually over time. This drug has been shown to be effective in the treatment of bowel disease, which may be due to its ability to decrease inflammation and increase the movement of stool through the intestines. Levothyroxine has also been shown to have beneficial effects on other autoimmune diseases such as rheumatoid arthritis and congestive heart failure. The use of levothyroxine requires periodic blood sampling for monitoring.
