    Chain A
    GO ID   Ontology GO Term Definition
    7271   Synaptic Transmission Cholinergic  The Process of Communication From a Neuron to a Target (neuron Muscle or Secretory Cell) Across a Synapse Using the Neurotransmitter Acetylcholine. 
    7584   Response to Nutrient  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 a Nutrient Stimulus. 
    7612   Learning  Any Process in an Organism in Which a Relatively Long Lasting Adaptive Behavioral Change Occurs As the Result of Experience. 
    8285   Negative Regulation of Cell Proliferation  Any Process That Stops Prevents or Reduces the Rate or Extent of Cell Proliferation. 
    14016   Neuroblast Differentiation  The Process in Which a Relatively Unspecialized Cell Acquires Specialized Features of a Neuroblast. There Are At Least Four Stages Through Which the Pluripotent Cells of Epiblast or Blastula Become Neuroblasts. 
    19695   Choline Metabolic Process  The Chemical Reactions and Pathways Involving Choline (2 Hydroxyethyltrimethylammonium) an Amino Alcohol That Occurs Widely in Living Organisms As a Constituent of Certain Types of Phospholipids and in the Neurotransmitter Acetylcholine. 
    42493   Response to Drug  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 a Drug Stimulus. a Drug Is a Substance Used in the Diagnosis Treatment or Prevention of a Disease. 
    43279   Response to Alkaloid  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 an Alkaloid Stimulus. Alkaloids Are a Large Group of Nitrogenous Substances Found in Naturally in Plants Many of Which Have Extracts That Are Pharmacologically Active. 
    44267   Cellular Protein Metabolic Process  The Chemical Reactions and Pathways Involving a Specific Protein Rather Than of Proteins in General Occurring At the Level of an Individual Cell. Includes Cellular Protein Modification. 
    50783   Cocaine Metabolic Process  The Chemical Reactions and Pathways Involving Cocaine an Alkaloid Obtained From the Dried Leaves of the Shrub Erythroxylon Coca. It Is a Cerebral Stimulant and Narcotic.

As a Result of a Glucocorticoid Stimulus. Glucocorticoids Are Hormonal C21 Corticosteroids Synthesized From Cholesterol with the Ability to Bind with the Cortisol Receptor and Trigger Similar Effects. Glucocorticoids Act Primarily On Carbohydrate and Protein Metabolism and Have Anti Inflammatory Effects.

Microparticles Are Heterogeneous in Size and Are Characterized As Microvesicles Free of Nucleic Acids. 
    1540   Beta Amyloid Binding  Interacting Selectively and Non Covalently with Beta Amyloid Peptide/protein And/or Its Precursor. 
    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. 
    3990   Acetylcholinesterase Activity  Catalysis of the Reaction: Acetylcholine + H2o = Choline + Acetate. 
    4104   Cholinesterase Activity  Catalysis of the Reaction: an Acylcholine + H2o = Choline + a Carboxylic Acid Anion. 
    16787   Hydrolase Activity  Catalysis of the Hydrolysis of Various Bonds E.g. C O C N C C Phosphoric Anhydride Bonds Etc. Hydrolase Is the Systematic Name For Any Enzyme of EC Class 3.
