The reaction of pepsin with bis-p-nitrophenyl sulfite has been studied at pH 2.2 and 25°C by observing the production of p-nitrophenol spectrophotometrically. Under the condition where the pepsin concentration is much greater than the ester concentration the observations suggest that the p-nitrophenol is not liberated in a single kinetic process.
