What Are The Functions Of Coenzymes?

Coenzymes are essential organic compounds that attach to enzymes to help them catalyze reactions. An enzyme has an active area where it catalyzes the reaction of a substrate but a coenzyme binds to other areas of the enzyme change shape and putting the active area to better fit the substrate. Many of coenzymes in the diet is essential vitamins we need to carry out reactions for cell function. The function of the coenzyme is taking an extra element to the reaction as an electron or functional group.
NAD
Nicotine adenine dinucleotide (NAD) is an electron carrier. It provides hydrogen ions for a number of oxidation-reduction reactions. The ring structure acts as an electron sink carrier choices to and from locations in the cell. NAD also functions in the metabolism of gathering electrons during catabolism donate electrons during anabolism.
coenzyme Q
Coq is another electron carrier that is lipid soluble. It’s membrane of the cell carrying electrons through the electron transport chain in the creation of adenosine triphosphate (ATP). Coq serves as a bridge between proteins in the mitochondria carrying electrons from complexes one and three and two and three. NAD in its reduced form the nicotine adenine dinucleotide hydrogen (NADH) the electrons travel Coq function.
Coenzyme A
CoA is an important coenzyme which functions as a two-carbon carrier sometimes known as acetyl group conveyor. CoA similar to NAD and flavin adenine dinucleotide (FAD) in the structure but the acetyl group attached to a thiol ester bond. CoA is basically in the citric acid cycle in mitochondria where ATP is made. It is also important in the breakdown of fatty acids.
FAD
FAD is also similar in structure to NAD but it has different functions. FAD also performs reactions such as flavin mononucleotide (FMN) and it contains riboflavin adenine ribose and phosphate. FMN also works in the electron transport chain in the compound. It acts as an oxidizing agent take electrons from NADH to go through the process.
Biotin
Biotin is an essential coenzyme but it can only be synthesized by few organisms such as bacteria yeast and mold. Biotin is a carboxylase carrier that provides the functional group for catalysis. It also functions in many reactions involving DNA histone interaction help relax DNA for replication and transcription activity.
