Iodine and L-tyrosine are different nutrient categories that meet in thyroid-hormone biochemistry. Iodine is a trace mineral obtained as iodide and handled by specialized transport and...

Thyroglobulin and thyroxine-binding globulin, shortened to TBG, have similar names but work in different places. Thyroglobulin is a very large protein made by thyroid follicular cells...

Monoiodotyrosine and diiodotyrosine are commonly shortened to MIT and DIT. Both begin as tyrosyl residues embedded within the large protein thyroglobulin. Thyroid peroxidase-guided chemistry adds one...

Iodine on a Supplement Facts panel is the starting material for a highly organized transport sequence. Thyroid cells move iodide across two membranes, oxidize it, attach...
