Studies on esterases in the chicken central nervous system

Abstract
The hydrolysis of various esters by chicken brain and spinal cord has been studied. The hydrolyses of phenyl phenylacetate and phenyl 3-phenyl-propionate have been studied in detail and the effects of various inhibitors determined. By using the organophosphorus compounds di-isopropyl phosphorofluoridate and NN''-di-isopropyl phosphorodi-amidic fluoride it has been established that phenyl phenylacetate and phenyl 3-phenylpropionate are hydrolysedby two or more esterases. These esterases are present in brain, spinal cord and sciatic nerve.
