Enzyme - Wikipedia
WEBEnzymes (/ ˈ ɛ n z aɪ m z /) are proteins that act as biological catalysts by accelerating chemical reactions. The molecules upon which enzymes may act are called substrates, and the enzyme converts the substrates into different molecules known as products.
Restriction enzyme - Wikipedia
WEBA restriction enzyme, restriction endonuclease, REase, ENase or restrictase is an enzyme that cleaves DNA into fragments at or near specific recognition sites within molecules known as restriction sites. Restriction enzymes are one class of the broader endonuclease group of enzymes.
Enzyme - Simple English Wikipedia, the free encyclopedia
WEBAn enzyme is a protein molecule in cells which works as a biological catalyst. [1] . Enzymes speed up chemical reactions in the body, but do not get used up in the process, so they can be used over and over again. Almost all …
Enzyme | Definition, Mechanisms, & Nomenclature | Britannica
WEBApr 16, 2024 · Enzyme, 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.
Digestive enzyme - Wikipedia
WEBTable of the different major digestive enzymes. Digestive enzymes are found throughout much of the gastrointestinal tract. In the human digestive system, the main sites of digestion are the mouth, stomach, and small intestine. Digestive enzymes are secreted by different exocrine glands including salivary glands, gastric glands, secretory cells ...
List of enzymes - Wikipedia
WEBList of enzymes. Enzymes are listed here by their classification in the International Union of Biochemistry and Molecular Biology 's Enzyme Commission (EC) numbering system : Category:Oxidoreductases (EC 1) ( Oxidoreductase) Dehydrogenase. Luciferase. DMSO reductase. Category:EC 1.1 (act on the CH-OH group of donors)
Enzyme kinetics - Wikipedia
WEBAn enzyme (E) is a protein molecule that serves as a biological catalyst to facilitate and accelerate a chemical reaction in the body. It does this through binding of another molecule, its substrate (S), which the enzyme acts upon to form the desired product.
Enzyme assay - Wikipedia
WEBIt is the micro moles of product formed by an enzyme in a given amount of time (minutes) under given conditions per milligram of total proteins. Specific activity is equal to the rate of reaction multiplied by the volume of reaction divided by the mass of total protein.
6.5: Enzymes - Biology LibreTexts
WEBA substance that helps a chemical reaction to occur is a catalyst, and the special molecules that catalyze biochemical reactions are called enzymes. Almost all enzymes are proteins, made up of chains of amino acids, and they perform the critical task of lowering the activation energies of chemical reactions inside the cell.
Enzyme structure and function (article) | Khan Academy
WEBEnzymes are biological catalysts--they catalyze the chemical reactions that happen inside living things. The definition of catalysis. Consider a chemical reaction where a molecule A bonds with a molecule B to create a molecule A-B (A stuck to B).
