    GO ID   Ontology GO Term Definition
    1516   Prostaglandin Biosynthetic Process  The Chemical Reactions and Pathways Resulting in the Formation of Prostaglandins Any of a Group of Biologically Active Metabolites Which Contain a Cyclopentane Ring. 
    6954   Inflammatory Response  The Immediate Defensive Reaction (by Vertebrate Tissue) to Infection or Injury Caused by Chemical or Physical Agents. the Process Is Characterized by Local Vasodilation Extravasation of Plasma Into Intercellular Spaces and Accumulation of White Blood Cells and Macrophages. 
    6979   Response to Oxidative Stress  Any Process That Results in a Change in State or Activity of a Cell or an Organism (in Terms of Movement Secretion Enzyme Production Gene Expression Etc.) As a Result of Oxidative Stress a State Often Resulting From Exposure to High Levels of Reactive Oxygen Species E.g. Superoxide Anions Hydrogen Peroxide (h2o2) and Hydroxyl Radicals. 
    8217   Regulation of Blood Pressure  Any Process That Modulates the Force with Which Blood Travels Through the Circulatory System. the Process Is Controlled by a Balance of Processes That Increase Pressure and Decrease Pressure. 
    19371   Cyclooxygenase Pathway  The Chemical Reactions and Pathways by Which Prostaglandins Are Formed From Arachidonic Acid and in Which Prostaglandin Endoperoxide Synthase (cyclooxygenase) Catalyzes the Committed Step in the Conversion of Arachidonic Acid to the Prostaglandin Endoperoxides Pgg2 and Pgh2. 
    55114   Oxidation Reduction Process  A Metabolic Process That Results in the Removal or Addition of One or More Electrons to or From a Substance with or Without the Concomitant Removal or Addition of a Proton or Protons. 
    4601   Peroxidase Activity  Catalysis of the Reaction: Donor + Hydrogen Peroxide = Oxidized Donor + 2 H2o. 
    4666   Prostaglandin Endoperoxide Synthase Activity  Catalysis of the Reaction: Arachidonate + Donor H2 + 2 O2 = Prostaglandin H2 + Acceptor + H2o. 
    20037   Heme Binding  Interacting Selectively and Non Covalently with Heme Any Compound of Iron Complexed in a Porphyrin (tetrapyrrole) Ring.
