2. Gastric acid - Wikipedia

   en.wikipedia.org/wiki/Gastric_acid

   The lowest pH of the secreted acid is 0.8, [7] but the acid is diluted in the stomach lumen to a pH of between 1 and 3. There is a small continuous basal secretion of gastric acid between meals of usually less than 10 mEq/hour. [8] There are three phases in the secretion of gastric acid which increase the secretion rate in order to digest a ...

3. Gastrointestinal physiology - Wikipedia

   en.wikipedia.org/wiki/Gastrointestinal_physiology

   H + is pumped into the stomach by exchanging it with K +. This process also requires ATP as a source of energy; however, Cl − then follows the positive charge in the H + through an open apical channel protein. HCO 3 − secretion occurs to neutralize the acid secretions that make their way into the duodenum of the small intestine.

4. Rennet - Wikipedia

   en.wikipedia.org/wiki/Rennet

   The crude rennet extract is then activated by adding acid; the enzymes in the stomach are produced in an inactive form and are activated by the stomach acid. The acid is then neutralized and the rennet extract is filtered in several stages and concentrated until reaching a typical potency of about 1:15,000; meaning 1 g of extract can coagulate ...

5. Vitamin B12 - Wikipedia

   en.wikipedia.org/wiki/Vitamin_B12

   A second major cause is an age-related decline in stomach acid production (achlorhydria), because acid exposure frees protein-bound vitamin. [12] For the same reason, people on long-term antacid therapy, using proton-pump inhibitors , [ 13 ] H 2 blockers or other antacids are at increased risk.

6. Food composition data - Wikipedia

   en.wikipedia.org/wiki/Food_composition_data

   The earliest food composition tables were based solely on chemical analyses of food samples, which were mostly undertaken specifically for the tables. However, as the food supply has evolved, and with the increasing demand for nutritional and related components, it has become more difficult for compilers to rely only on chemical analysis when ...

7. Sodium bicarbonate - Wikipedia

   en.wikipedia.org/wiki/Sodium_bicarbonate

   [38] [39] Its reaction with stomach acid produces salt, water, and carbon dioxide: NaHCO 3 + HCl → NaCl + H 2 O + CO 2 (g) A mixture of sodium bicarbonate and polyethylene glycol such as PegLyte, [ 40 ] dissolved in water and taken orally, is an effective gastrointestinal lavage preparation and laxative prior to gastrointestinal surgery ...

8. Mucus - Wikipedia

   en.wikipedia.org/wiki/Mucus

   The chief and parietal cells produce and secrete mucus (F) to protect the lining of the stomach (C) against the harsh pH of stomach acid. The mucus is basic, while the stomach acid (A) is acidic. In the human digestive system, mucus is used as a lubricant for materials that must pass over membranes, e.g., food passing down the esophagus.

9. Bicarbonate - Wikipedia

   en.wikipedia.org/wiki/Bicarbonate

   It is isoelectronic with nitric acid HNO 3. The bicarbonate ion carries a negative one formal charge and is an amphiprotic species which has both acidic and basic properties. It is both the conjugate base of carbonic acid H 2 CO 3; and the conjugate acid of CO 2− 3, the carbonate ion, as shown by these equilibrium reactions: CO 2− 3 + 2 H 2 ...
