3026-2Thyroxine (T4) [Mass/volume] in Serum or PlasmaActive

Part Description

LP15900-1   Thyroxine
The major hormone derived from the thyroid gland. Thyroxine is synthesized via the iodination of tyrosine (monoiodotyrosine) and the coupling of iodotyrosine (diiodotyrosine) in thyroglobulin. Thyroxine is separated from thyroglobulin by proteolysis and released in the blood. Thyroxine is peripherally deiodinated to form triiodothyronine which exerts broad stimulatory effects on cell metabolism.
