Synonyms Used in print (The Times-Picayune, [New Orleans]...)writes : Does the cholesterol go_down when most of the thyroid_gland is removed ? (Jacob Robbins et al., "The thyroid-stimulating...)In the thyroid_gland it appears that proteins ( chiefly thyroglobulin ) are iodinated and that free tyrosine and thyronine are not iodinated . Since the circulating thyroid_hormones are the amino_acids thyroxine and tri-iodothyronine ( cf. Section C ) , it is clear that some mechanism must exist in the thyroid_gland for their release from proteins before secretion . The finding that the concentration of one of these proteases is increased in thyroid_glands from TSH treated animals suggests that this protease may be active in_vivo . Besides the presence of goitrogens in the diet , the level of iodine itself in the diet plays a major role in governing the activity of the thyroid_gland . Related terms |
