Levothyroxine T4 (0.2mg/60caps)

Levothyroxine (L-thyroxine, T4) is an iodinated amino acid derivative utilized as a reference compound in studies of thyroid hormone biochemistry, metabolism, and signaling. It serves as a substrate for deiodinase enzymes (DIO1, DIO2, and DIO3), which catalyze selective deiodination reactions and regulate downstream thyroid hormone-associated molecular pathways. Experimental investigations have employed T4 in studies of deiodinase enzymology, thyroid hormone transport proteins, nuclear receptor signaling, transcriptional regulation, metabolic pathway modulation, and endocrine signaling networks. Its well-characterized biochemical properties make it a valuable research tool for investigations of thyroid hormone metabolism, deiodinase-dependent conversion mechanisms, receptor-mediated signaling pathways, and comparative analyses of thyroid hormone-associated molecular processes. Supplied in capsule format.
