Hans von Euler-Chelpin described the role of enzymes in the process of fermentation and also researched vitamins, tumors, enzymes, and coenzymes. He was an important contributor in the discovery of the structure of certain vitamins. In 1929, he shared the Nobel Prize in chemistry with Arthur Harden for their research on the fermentation of sugar and enzymes. Euler-Chelpin's research has far-reaching implications in the fields of nutrition and medicine.
