1932E. Stedman et al. in Biochem. Jrnl. XXVI. 2059 It is proposed to term the enzyme which hydrolyses esters of choline choline-esterase. 1944Ann. Reg. 1943 353 Brain tissue of all vertebrates was found to contain only true cholinesterase, which hydrolyses low concentrations of acetylcholine, and plays an essential role in the chemical transmission of nerve impulses. 1956Nature 28 Jan. 185/2 Most of our knowledge concerning the topical distribution of cholinesterases in the mammalian nervous system is derived from studies on tissue sections. 1963Listener 7 Feb. 238/2 Agents which upset the so-called ‘choline-esterase’ mechanism by means of which nerves transmit their messages were at one time recommended as war weapons but they now appear to be considered old fashioned. |
