A Nearly Universal Metabolic Pathway in Which the Acetyl Group of Acetyl Coenzyme a Is Effectively Oxidized to Two Co2 and Four Pairs of Electrons Are Transferred to Coenzymes. the Acetyl Group Combines with Oxaloacetate to Form Citrate Which Undergoes Successive Transformations to Isocitrate 2 Oxoglutarate Succinyl Coa Succinate Fumarate Malate and Oxaloacetate Again Thus Completing the Cycle. in Eukaryotes the Tricarboxylic Acid Is Confined to the Mitochondria. See Also Glyoxylate Cycle.
The Chemical Reactions and Pathways Involving Isocitrate the Anion of Isocitric Acid 1 Hydroxy 1 2 3 Propanetricarboxylic Acid. Isocitrate Is an Important Intermediate in the Tca Cycle and the Glycoxylate Cycle.
Catalysis of an Oxidation Reduction (redox) Reaction a Reversible Chemical Reaction in Which the Oxidation State of an Atom or Atoms Within a Molecule Is Altered. One Substrate Acts As a Hydrogen or Electron Donor and Becomes Oxidized While the Other Acts As Hydrogen or Electron Acceptor and Becomes Reduced.
Interacting Selectively and Non Covalently with Nicotinamide Adenine Dinucleotide a Coenzyme Involved in Many Redox and Biosynthetic Reactions; Binding May Be to Either the Oxidized Form Nad+ or the Reduced Form Nadh.
