Digestive enzyme - Wikipedia
WebGastric enzymes that can digest protein can also digest the stomach itself. The stomach is protected from self-digestion by the mucosal barrier. This barrier has several components. First, the stomach wall is covered by a thick coating of bicarbonate-rich mucus. This mucus forms a physical barrier, and its bicarbonate ions neutralize acid. In inorganic chemistry, bicarbonate (IUPAC-recommended nomenclature: hydrogencarbonate ) is an intermediate form in the deprotonation of carbonic acid. It is a polyatomic anion with the chemical formula HCO 3. Bicarbonate serves a crucial biochemical role in the physiological pH buffering system. The term "bicarbonate" was coined in 1814 by the English chemist William Hyde Wollaston. The … WebIt is quite possible that bicarbonate in water may play a buffering role in the case of people sensitive to gastric acidity. Thus bicarbonate may be helpful for digestion.
