Bookmark or Share- Biochemistry, Proteins Enzymes - StatPearls - NCBI BookshelfThere are six main categories of enzymes: oxidoreductases, transferases, hydrolases, lyases, isomerases, and ligases. Each category carries out a general type of reaction but catalyzes many different specific reactions within their own category.
- Enzyme | Definition, Mechanisms, & Nomenclature | BritannicaEnzyme, a catalyst that regulates the rate at which chemical reactions proceed in living organisms without itself being altered in the process. Most critically, enzymes catalyze all aspects of cell metabolism. Learn more about enzymes in this article.
- Enzyme: Definition, Types, Structure, Functions, & DiagramEnzymes are protein macromolecules that are necessary to initiate or speed up the rate of chemical reactions in the bodies of living organisms. The molecules on which enzymes act are called substrates, and the substance formed is called the product. They are found in all living cells that vary in type based on the function it performs.
- The Central Role of Enzymes as Biological CatalystsA fundamental task of proteins is to act as enzymes—catalysts that increase the rate of virtually all the chemical reactions within cells. Although RNAs are capable of catalyzing some reactions, most biological reactions are catalyzed by proteins.
- Enzymes: principles and biotechnological applications - PMCEnzymes are biological catalysts (also known as biocatalysts) that speed up biochemical reactions in living organisms. They can also be extracted from cells and then used to catalyse a wide range of commercially important processes.
