Biochem/physiol Actions
Pepsinogen is the zymogen of pepsin. It is processed by autocatalytic cleavage of 44 amino acids to generate active pepsin. Serum levels of pepsinogen have been measured to identify gastric cancer risk.
Analysis Note
Protein determined by biuret.
Other Notes
One unit will produce a ΔA280 of 0.001 per min at pH 2.0 at 37 °C, measured as TCA-soluble products, using hemoglobin as substrate. (Final volume = 16 mL. Light path = 1 cm.)
