thyroxine and Aging

thyroxine has been researched along with Aging in 814 studies

Thyroxine: The major hormone derived from the thyroid gland. Thyroxine is synthesized via the iodination of tyrosines (MONOIODOTYROSINE) and the coupling of iodotyrosines (DIIODOTYROSINE) in the THYROGLOBULIN. Thyroxine is released from thyroglobulin by proteolysis and secreted into the blood. Thyroxine is peripherally deiodinated to form TRIIODOTHYRONINE which exerts a broad spectrum of stimulatory effects on cell metabolism.
thyroxine : An iodothyronine compound having iodo substituents at the 3-, 3'-, 5- and 5'-positions.

Aging: The gradual irreversible changes in structure and function of an organism that occur as a result of the passage of time.
