Water Metabolism Pathway

Water metabolism pathway" is not a specific molecular target such as a receptor, enzyme, or transporter. Instead, it refers to the integrated physiological processes that regulate the intake, distribution, and excretion of water in the body. This includes mechanisms controlling fluid compartments (intracellular vs. extracellular), hormonal regulators like antidiuretic hormone (ADH/vasopressin), thirst response mediated by hypothalamic sensors, renal handling via reabsorption/excretion in nephrons under hormonal control (ADH and aldosterone), and feedback systems maintaining plasma osmolality and serum sodium levels. Disruptions in this pathway can lead to clinical conditions such as dehydration or disorders like hyponatremia/hypernatremia. The "water metabolism pathway" is thus a broad physiological concept rather than an individual druggable target or molecule.
