The video explores the biosynthesis of thyroid hormones, focusing on T3 (triiodothyronine) and T4 (tetraiodothyronine). It explains the role of thyroglobulin and the iodination process, detailing the activation of iodide and the mechanism of iodination of tyrosine residues. The video also covers the radical mechanism involved in synthesizing T3 and T4, and discusses the function of thyroxine in regulating metabolic rate. Additionally, it touches on hypothyroidism and the use of levothyroxine as a treatment.
