There are some diseases that we must live with, called chronic diseases, such as diabetes.
Fortunately, as science progresses, people suffering from these diseases can lead a more normal life. In order to improve our knowledge, the first thing we must find out is why we suffer from these diseases.
Dorothy Hodgkin, a chemist born in Cairo (Egypt) in 1910, discovered the three-dimensional structures of many molecules with an X-ray diffraction apparatus. Some are well known, such as Cholesterol, a type of fat we worry about; penicillin, an antibiotic to treat diseases caused by bacteria; Vitamin B12, to prevent anaemia; or insulin, which was the subject of Dorothy’s main research work.
Artificial insulin is the substance needed by a patient with diabetes, so scientific knowledge about insulin is essential to understand and to fight this disease.
