The synthesis of ADH occurs in the ribosomes and proceeds via the formation of a macromolecular precursor or prohormone. This precursor or propressophysin has a molecular weight of about 20,000 Da. The prohormone contains several subunits, each of which has a biological function. One of these subunits, ADH, is preceded by a signal peptide. When the osmoreceptors located in the anterolateral hypothalamus perceive a change in the osmolarity of the blood (normal range: 275-290 mOsm\/kg), this signal peptide is alerted and ADH is released. ADH binds to receptors in the glomerulus and renal convoluted tubules with the result that water is reabsorbed. The sensitivity of the system is affected by the physiological status of the individual. For example, the phase of the menstrual cycle in females affects the sensitivity to the action of ADH such that water balance (water retention) varies through the cycle.A hormone produced by the pituitary gland, which controls how much fluid remains in the body and how much is excreted in urine. Lack of ADH can trigger diabetes insipidus.A peptide hormone that plays a crucial role in limiting the amount of water excreted by the kidneys. Deficiency of ADH causes central diabetes insipidus, excess causes water retention and hyponatremia."}
