Though it is not the typical route of production, small amounts of this compound are synthesized in the (*) follicular lumen by the coupling of MIT and DIT.
Adding this compound to traditional medications such as tricyclics and SSRIs has shown positive results in treating patients with refractory depression. The so-called "Antarctic stare" is a cognitive impairment caused by the reduction of this compound in polar explorers. The binding saturation of this compound can be tested by a namesake "resin reuptake assay." The placenta contains the type III form of a selenium-dependent enzyme, which converts this compound's precursor into an inactive "reverse" type of this compound. Though it is not the typical route of production, small amounts of this compound are synthesized in the (*) follicular lumen by the coupling of MIT and DIT. This hormone's activity can be summarized by the 4 B's: brain maturation, beta-adrenergic effects, increased basal metabolic rate, and bone growth. This is the less massive of two hormones that are overproduced in Graves's disease. For 10 points, name this thyroid hormone which is produced from the deiodination of T4.
