Wind can carry acid rain dust around the globe far from the source of the pollution. The U.S. tracks the chemicals in acid rain. The Northeastern region is the most acidic because it has many power and industrial plants, people, and cities. Many plants in the Midwest release harmful chemi...
It is known that taste receptors for bitter substances are not only found on the tongue, but also on the surface of other tissues and cells. These include the parietal cells of the stomach, which secrete protons into the stomach – i.e. produce gastric acid. Recent studies have already sho...
The stomach is one of the organs of the gastrointestinal tract. The stomach receives the food for digestion, it secretes the acids and digestive juices. The stomach acid is hydrochloric acid, which kills the microbes present in food to split up the proteins....
Colonization of Helicobacter pylori in the acidic environment of the human stomach depends on the neutralizing activity of urease. Activation of apo-urease... Yu,Hang,Fong,... - 《Journal of Biological Chemistry》 被引量: 30发表: 2011年 ...
Bicarbonate is alkaline, a base, and neutralizes the acid secreted by the parietal cells, producing water in the process. This continuous supply of bicarbonate is the main way that your stomach protects itself from autodigestion (the stomach digesting itself) and the overall acidic environment. ...
A buffer system is responsible for keeping the pH at a specific level in which they are present. A buffer prohibits the changes in the pH of a solution due to the introduction fo an acid or a base in the solution. A buffer is formed with acid and its conjugate base in the solution....
The silver nitrate is a catalyst, a substance that makes a reaction go faster without participating in it. The sulfuric acid, in addition to removing the alcohol from the air, also might provide the acidic condition needed for this reaction. During this reaction, the reddish-orange dichromate ...
What is the meaning of the "-" in HCO3-? Why do the bodies cells become more acidic as a result of cellular respiration? Explain the buffer system in the blood. Explain how hemoglobin effectively delivers oxygen to myoglobin in muscles. ...
One such method is developing degradation-resistant VLPs that can endure the highly acidic environmental conditions of the stomach following oral immunization. This can be achieved by exploiting the structural components of gastrointestinal protozoan parasites such as Giardia lamblia. The cysteine-rich ...
