    GO ID   Ontology GO Term Definition
    5975   Carbohydrate Metabolic Process  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. 
    8152   Metabolic Process  The Chemical Reactions and Pathways Including Anabolism and Catabolism by Which Living Organisms Transform Chemical Substances. Metabolic Processes Typically Transform Small Molecules But Also Include Macromolecular Processes Such As DNA Repair and Replication and Protein Synthesis and Degradation. 
    9063   Cellular Amino Acid Catabolic Process  The Chemical Reactions and Pathways Resulting in the Breakdown of Amino Acids Organic Acids Containing One or More Amino Substituents. 
    16052   Carbohydrate Catabolic Process  The Chemical Reactions and Pathways Resulting in the Breakdown of Carbohydrates Any of a Group of Organic Compounds Based of the General Formula Cx(h2o)y. 
    287   Magnesium Ion Binding  Interacting Selectively and Non Covalently with Magnesium (mg) Ions. 
    3824   Catalytic Activity  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. 
    8927   Mannonate Dehydratase Activity  Catalysis of the Reaction: D Mannonate = 2 Dehydro 3 Deoxy D Gluconate + H(2)o. 
    16829   Lyase Activity  Catalysis of the Cleavage of C C C O C N and Other Bonds by Other Means Than by Hydrolysis or Oxidation or Conversely Adding a Group to a Double Bond. They Differ From Other Enzymes in That Two Substrates Are Involved in One Reaction Direction But Only One in the Other Direction. When Acting On the Single Substrate a Molecule Is Eliminated and This Generates Either a New Double Bond or a New Ring. 
    46872   Metal Ion Binding  Interacting Selectively and Non Covalently with Any Metal Ion. 
    47929   Gluconate Dehydratase Activity  Catalysis of the Reaction: D Gluconate = 2 Dehydro 3 Deoxy D Gluconate + H(2)o.
