Deoxycorticosterone is a precursor molecule for the production of aldosterone. The major pathway for aldosterone production is in the adrenal glomerulosa zone of the adrenal gland. It is not a major secretory hormone. It is produced from progesterone by 21β-hydroxylase and is converted to corticosterone by 11β-hydroxylase.
