Etymology

The word 'enzyme' was coined in the late 19th century from the Modern Latin 'enzyma', which itself was derived from the Greek elements 'en-', meaning 'in', and 'zymē', meaning 'leaven'. The term was created to describe the biological catalysts found 'in leaven' or yeast that were responsible for fermentation. This naming directly links the ancient, observable process of fermentation caused by yeast to the modern scientific understanding of proteins that accelerate specific chemical reactions within cells. The logic of the word captures the concept of an active agent working within a substance to induce change.

Analysis
