How does ph affect pepsin
WebNational Center for Biotechnology Information WebAs the pH rises above 4, pepsin activity decreases or stops. Some types of antacids, made of sodium bicarbonate (NaHCO 3) or calcium carbonate (CaCO 3 ), are easily absorbed into a person’s body and can cause a pH imbalance, possibly leading to kidney damage or other problems (Berkow, 1987).
