UREA INHIBITION OF HUMAN PSEUDOCHOLINESTERASEA

Abstract
A method for differentiating between the usual and atypical pseudocholinesterases in serum using urea is described. The method can be used for detecting suxamethonium-sensitive individuals. The results from studies of urea inhibition indicate that the atypical pseudocholinesterase is less stable in its tertiary protein structure than is the usual enzyme.
