aquaporin

Aquaporins are specialized protein channels embedded in cell membranes that facilitate the rapid movement of water molecules in and out of cells. They are essential for maintaining water balance within the body, supporting processes like kidney function, brain hydration, and cell hydration. By allowing water to pass efficiently, aquaporins help regulate fluid levels, ensure proper cell function, and respond to changes in hydration or osmotic pressure. In essence, they act as gateways that precisely control water flow, playing a crucial role in many physiological functions related to fluid regulation.
