The Chemical Reactions and Pathways Involving Carbohydrates Any of a Group of Organic Compounds Based of the General Formula Cx(h2o)y. Includes the Formation of Carbohydrate Derivatives by the Addition of a Carbohydrate Residue to Another Molecule.
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 Malate the Anion of Hydroxybutanedioic Acid a Chiral Hydroxydicarboxylic Acid. the (+) Enantiomer Is an Important Intermediate in Metabolism As a Component of Both the Tca Cycle and the Glyoxylate Cycle.
Interacting Selectively and Non Covalently with a Nucleotide Any Compound Consisting of a Nucleoside That Is Esterified with (ortho)phosphate or an Oligophosphate At Any Hydroxyl Group On the Ribose or Deoxyribose.
Catalysis of a Biochemical Reaction At Physiological Temperatures. in Biologically Catalyzed Reactions the Reactants Are Known As Substrates and the Catalysts Are Naturally Occurring Macromolecular Substances Known As Enzymes. Enzymes Possess Specific Binding Sites For Substrates and Are Usually Composed Wholly or Largely of Protein But RNA That Has Catalytic Activity (ribozyme) Is Often Also Regarded As Enzymatic.
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.
