Hydrochloric Acid: Physiological Functions and Clinical Implications
Hydrochloric acid (HCl) secretion assists protein digestion by activating pepsinogen to pepsin, renders the stomach sterile against orally-ingested pathogens, prevents bacterial or fungal overgrowth of the small intestine, encourages the flow of bile and pancreatic enzymes, and facilitates the absorption of a variety of nutrients, including folic acid, ascorbic acid, beta-carotene, non-heme iro...
متن کاملThe Combination of Edestin with Hydrochloric Acid
Electromotive force measurements of cells without liquid junction, of the type Ag, AgCl, HCl + protein, H(2), lead to the conclusion that 1 gm. of edestin (or, more probably, edestan) combines with a maximum of 13.4 x 10(-4) equivalents of H(+) and 3.9 x 10(-4) equivalents of Cl(-), when the protein is dissolved in 0.1 M HCl.
متن کاملThe Combination of Gelatin with Hydrochloric Acid
1. Cooper's gelatin purified according to Northrop and Kunitz exhibited a minimum of osmotic pressure and a maximum of opacity at pH 5.05 +/-0.05. The pH of solutions of this gelatin in water was also close to this value. It is inferred that such gelatin is isoelectric at this pH and not at pH 4.70. 2. Hydrogen electrode measurements with KCl-agar junctions were made with concentrated solutions...
متن کاملInvestigation of Furfural as Corrosion Inhibitor in Hydrochloric Acid Solution
Effectiveness of furfural as an organic inhibitor in 5 percent hydrochloric acid which is used in acid pickling of steel was evaluated. Lungmuir, Frumkin and Flory-Huggins isotherms [1, 2] were used to determine the parameters of effective adsorption, free energy and entropy of adsorption. Furfural indicated an inhibition less than 17 percent in concentrations of 0.001 mole per liter for a dura...
متن کاملReduced mobility of di-propylene glycol methylether in its aqueous mixtures by quasielastic neutron scattering.
The hydrogen (H-) bonding interplay between water and other organic molecules is important both in nature and in a wide range of technological applications. Structural relaxation and, thus, diffusion in aqueous mixtures are generally dependent on both the strength and the structure of the H-bonds. To investigate diffusion in H-bonding mixtures, we present a quasielastic neutron scattering study...
