The term enzyme comes from zymosis, the Greek word for fermentation
, a process accomplished by yeast cells and long known to the brewing industry, which occupied the attention of many 19th-century chemists.
Louis Pasteur recognized in 1860 that enzymes were essential to fermentation but assumed that their catalytic action was inextricably linked with the structure and life of the yeast cell. Not until 1897 was it shown by German chemist Edward Büchner that cell-free extracts of yeast could ferment sugars to alcohol and carbon dioxide; Büchner denoted his preparation zymase. This important achievement was the first indication that enzymes could function independently of the cell.
