Cofactor (biochemistry) - Wikipedia
A cofactor is a non-protein chemical compound or metallic ion that is required for an enzyme's role as a catalyst (a catalyst is a substance that increases the rate of a chemical reaction). Cofactors can be considered "helper molecules" that assist in biochemical transformations.
Cofactor - Definition, Types and Examples | Biology Dictionary
2017年4月27日 · A cofactor is a non-protein chemical that assists with a biological chemical reaction. Co-factors may be metal ions, organic compounds, or other chemicals that have helpful properties not usually found in amino acids.
Enzyme Cofactors: Types, Functions, and Examples of Enzyme
A cofactor is a chemical or metallic ion that is not a protein and is necessary for the catalytic function of an enzyme (a catalyst increases the rate of a chemical reaction).
Cofactor | Cofactor of A Matrix, Formula (With Solved Example)
A cofactor is a number that is obtained by eliminating the row and column of a particular element which is in the form of a square or rectangle. The cofactor is preceded by a negative or positive sign based on the element’s position.

2024年8月25日 · Even though no cofactor is required, nucleophilic catalysis by an amine through Schiff Base formation would speed up the reaction (as we will see below). Now let's look at how some of the cofactors listed in Table \(\PageIndex{1}\) above facilitate electron flow in reactions.
Cofactor | Vitamins, Enzymes, Metabolism | Britannica
cofactor, a component, other than the protein portion, of many enzymes. If the cofactor is removed from a complete enzyme (holoenzyme), the protein component (apoenzyme) no longer has catalytic activity.
Cofactor - Biology Simple
2024年3月5日 · A cofactor is a non-protein compound that helps enzymes perform chemical reactions efficiently. It can be organic or inorganic. Cofactors are essential for enzyme function as they assist in catalyzing biochemical reactions.
What is an Enzyme Cofactor? - News-Medical.net
2023年7月18日 · Ascorbic acid, or vitamin C, is used as a cofactor in hydroxylases. One hydroxylase which needs vitamin C is the enzyme which catalyze the hydroxylation of proline and lysine, two amino acids.
Enzyme Cofactors - ChemTalk
Each type of cofactor helps chemically modify a reaction, and they tend to play an irreplaceable role in most cases. For reactions that depend on cofactors, enzymes can be rendered an inactive “apoenzyme” without the presence of their cofactor.
