Roles Classification
Chemical Role(s): nucleophilic reagent
A reagent that forms a bond to its reaction partner (the electrophile) by donating both bonding electrons.
Biological Role(s): EC 3.5.1.4 (amidase) inhibitor
An EC 3.5.1.* (non-peptide linear amide C-N hydrolase) inhibitor that interferes with the action of amidase (EC 3.5.1.4).
metabolite
Any intermediate or product resulting from metabolism. The term 'metabolite' subsumes the classes commonly known as primary and secondary metabolites.
neurotoxin
A poison that interferes with the functions of the nervous system.
Application(s): refrigerant
A substance used in a thermodynamic heat pump cycle or refrigeration cycle that undergoes a phase change from a gas to a liquid and back. Refrigerants are used in air-conditioning systems and freezers or refrigerators and are assigned a "R" number (by ASHRAE - formerly the American Society of Heating, Refrigerating and Air Conditioning Engineers), which is determined systematically according to their molecular structure.
nucleophilic reagent
A reagent that forms a bond to its reaction partner (the electrophile) by donating both bonding electrons.
