Description
Liothyronine (T3) is a synthetic form of triiodothyronine, a bioactive iodinated compound involved in various metabolic and biochemical pathways. It is structurally distinct due to its higher receptor affinity compared to its precursor, thyroxine (T4).
T3 primarily undergoes deiodination, sulfation, and glucuronidation, contributing to its metabolic turnover and regulatory functions. It exhibits lower plasma protein binding (~46%) compared to T4, allowing for increased bioavailability and rapid interactions with target molecules. The compound is processed through enzymatic deactivation and excretion pathways, ensuring controlled molecular activity.
