Review of the own and literature data on substrate specificity with use of thiosubstrates for cholinesterases of various species. Dependence of cholinesteratic hydrolysis parameters on various elements of their structure is considered: the acyl part, alkyl "bridge" between ester atom and onion group, and ammonium grouping of molecule of 44 thioesters. A comparative enzymological analysis of the substrate specificity is performed with use of thiocholine esters of acetic, propionic, and butyric acids for 40 cholinesterase preparations of mammals, insects, molluscs, and plants.
