carbamate insecticide Derivatives of carbamic acid with insecticidal properties of general formula ROC(=O)NR1R2, where ROH is an alcohol, oxime, or phenol and R1 is hydrogen or methyl. Like organophosphate insecticides, they are cholinesterase inhibitors, but carbamate insecticides differ in action from the organophosphates in that the inhibitory effect on cholinesterase is generally brief. EC 3.1.1.7 (acetylcholinesterase) inhibitor An EC 3.1.1.* (carboxylic ester hydrolase) inhibitor that interferes with the action of enzyme acetylcholinesterase (EC 3.1.1.7), which helps breaking down of acetylcholine into choline and acetic acid.
