What is T4 (Thyroxine / Levothyroxine)?

T4 (Thyroxine/Levothyroxine) is the primary secretory product of the thyroid gland — a prohormone converted to active T3 (triiodothyronine) by deiodinase enzymes. Acts on thyroid receptors (TRα/TRβ) to regulate metabolism, thermogenesis, cardiac function, and gene expression. Research tool for thyroid hormone pharmacology, metabolic rate, and HPT axis studies. Research use only.

Research Applications

T4-to-T3 Conversion

Deiodinase enzyme activity, tissue-specific T3 production, substrate kinetics

Thyroid Receptor Pharmacology

TRα vs TRβ selectivity, nuclear receptor binding, TRE-mediated transcription

Metabolic Rate Research

Basal metabolic rate upregulation, thermogenesis, mitochondrial uncoupling interaction

HPT Axis Research

Hypothalamic-pituitary-thyroid feedback — TSH suppression, TRH regulation

Cardiac Thyroid Research

TRα-mediated cardiac chronotropy, myosin heavy chain isoform switching
