Goiter is associated with deficiency of which mineral?
Goitre is associated with Iodine deficiency.
Iodine is essential for the thyroid hormone formation.
Tri-iodothyronine and tetra-iodothyronine are the thyroid
hormones.
They are formed by the iodination of thyroglobulin.
Thyroglobulin undergoes iodination to form mono-iodothyronine and
di-iodothyronine.
Mono-iodothyronine combines with di-iodothyronine to form
tri-iodothyronine.
Di-iodothyronine combines with another di-iodothyronine molecule to
form tetra-iodothyronine.
