DIGESTIVE ENZYMES NO FURTHER A MYSTERY

Oxyntic glands also contain Main cells that secrete the zymogen pepsinogen. Pepsinogen may be the precursor to the proteolytic enzyme pepsin and has to be activated to pepsin because of the acidic pH of the abdomen (beneath three.five) or from autoactivation by pepsin by itself. Pepsin then acts on the internal peptide bonds of proteins in the best
