Biochem/physiol Actions

Pepsin is a component of gastric juice and is associated with protein digestion. It is an endopeptidase that catalyzes the degradation of proteins into peptides and amino acids for small intestinal absorption. Pepsin is released as a zymogen (pepsinogen) by the chief cells of the gastric lining. It gets activated by the acidic environment created by the hydrochloric acid (HCl) of gastric juice. Pepsin is active at pH 1.5 to 2, in the stomach. It is involved in the conversion of food bolus into chyme. It is associated with laryngopharyngeal reflux (LPR) indicated by chronic cough, mild dysphagia, hoarseness, and non-productive throat clearing.

Questions

  1. Would I like to know is the lyophilized powder units/mg protein in this Pepsin

    1 answer
    1. Yes, this product activity is measured as ≥ 0.70 FIP-U/mg. There is no conversion factor for FIP to other units, the customer has to determine the conversion factor experimentally. The FIP unit is the measurement of enzymatic activity according to test methods of the Federation Internationale Pharmaceutique. One FIP Unit of pepsin is expressed as micromoles of porcine gastric mucosa equivalents liberated per minute at 25°C.
