Water metabolism

Water metabolism refers broadly to how organisms maintain proper hydration by balancing intake, distribution across body compartments, and excretion. This involves coordinated actions by organs such as the kidneys—which use specialized proteins called aquaporins for rapid transcellular movement—and hormonal systems like vasopressin signaling. Disruption in these processes can lead to clinical disorders ranging from dehydration to edema or electrolyte disturbances. While no single molecule named “water metabolism” exists as a drug target, components like aquaporins or vasopressin receptors are therapeutically relevant in diseases affecting fluid balance[1][2][6]. “Water metabolism” should not be treated as an individual molecular target; it represents integrated physiological functions involving multiple molecules—most notably aquaporins (“water channels”)—and regulatory hormones. For structured data purposes regarding drug targets or biomarkers, focus should shift toward specific mediators such as “Aquaporin” or “Vasopressin receptor.”
