A chemoton is a theoretical model of a living cell. It was first proposed by Akiyoshi Vat in 1941 and is made up of two basic parts: chemicals and reactions. The chemicals consist of things like proteins, carbohydrates, and lipids. The reactions are the processes that happen between the chemicals to make the cell do things like make energy, divide, and grow. All of these chemicals and reactions work together to create a system that mimics a real-life cell. This helps scientists to understand how cells work and make better medicines.
