Aquaporins

Aquaporins are specialized protein channels embedded in cell membranes that facilitate the rapid movement of water molecules in and out of cells. They act like tiny gates, allowing water to pass efficiently while blocking most other substances. This regulation of water flow is essential for maintaining proper hydration, cell shape, and functions across various organs, including the kidneys, brain, and eyes. Aquaporins play a key role in processes such as urine concentration, brain fluid balance, and skin hydration, helping the body manage water effectively in response to different physiological needs.
