Chemistry contributes to improving human health and well-being by providing insights into the chemical processes that occur in living organisms and the interactions between drugs and the human body. This knowledge is used to develop new drugs, understand how diseases occur, and develop new treatments for illnesses. For example, chemistry is used to create new antibiotics, develop cancer treatments, and design drugs to treat neurological disorders. Advances in chemistry have led to many medical breakthroughs that have improved human health and saved countless lives.
