Definition(s)

A protein that speeds up chemical reactions in the body.: Definition from: Physician Data Query via Unified Medical Language System at the National Library of Medicine
An enzyme is a biological catalyst and is almost always a protein. It speeds up the rate of a specific chemical reaction in the cell. The enzyme is not destroyed during the reaction and is used over and over. A cell contains thousands of different types of enzyme molecules, each specific to a particular chemical reaction.: Definition from: Talking Glossary of Genetic Terms from the National Human Genome Research Institute
