Examples
- Triiodothyronine is synthesized from thyroxine in peripheral tissues where it exerts the same biological effects as thyroxine but is more potent and briefer.
- Triiodothyronine is one of the hormones produced by the thyroid gland and is a more potent form of thyroxine with one less iodine atom per molecule.
- Doctors measure the levels of triiodothyronine in the blood to diagnose and monitor thyroid disorders, especially in patients who are suspected to have hypothyroidism.
- In comparison to thyroxine, triiodothyronine is produced in much smaller quantities by the thyroid gland but has a more significant impact on metabolism.
- Conversion of thyroxine to triiodothyronine is crucial for maintaining proper thyroid function as it allows the more potent form of the hormone to exert its effects at the cellular level.
