Why sea fish don’t mind salty water? Researchers exploring cellular interplay of molecules

For marine animals, it is crucial that the pressure in their cells – the so-called osmotic pressure – stays on a level which allows them to survive in salty water. Without adjusting pressure, the cells would implode or explode. In recent research, it has been found that two different molecules are responsible for controlling the inner cell pressure. These molecules are called Trimethylamine-N-oxide (TMAO) and urea. However, up to now, it was still unclear why two different molecules are needed. Together with international collaborators, researchers at the Max Planck Institute for Polymer Research solved this puzzle. (Mehr in: Pressemitteilungen – idw – Informationsdienst Wissenschaft)
