Nonenzymatic is a term used to describe a process that does not involve enzymes. Synonyms for nonenzymatic include noncatalytic, uncatalyzed, non-enzymal, and non-bio-enzymic. These terms are useful in differentiating chemical reactions that are not facilitated by enzymes from those that are. Nonenzymatic reactions are typically slower and less efficient compared to their enzymatic counterparts, making them less common in biological systems. However, they still play an essential role in many chemical and physical processes. By using these synonyms, researchers can properly classify different types of reactions and better understand their properties and mechanisms.
