Peter Agre

Peter Agre is an American biochemist who contributed significantly to our understanding of how water moves in and out of cells. He discovered aquaporins, which are special proteins that form channels in cell membranes, allowing water to pass through while blocking other molecules. This discovery has implications for various fields, including medicine and agriculture, as it helps explain how cells regulate water balance, affecting kidney function and plant hydration. In 2003, Agre received the Nobel Prize in Chemistry for his work, highlighting the importance of molecular biophysics in understanding life at the cellular level.
