Acids: Acids are substances that are made up of molecules that can donate or give off hydrogen ions (H+). Acids have a pH less than 7, and they can usually dissolve metals and have a sour taste. Examples of acids include hydrochloric acid (found in gastric juice), uric acid (found in...
i.e., oxidation is happening in between them. This happens because oxygen,being highly electronegative,accepts these electronsfrom metal, which are quitelooselybonded to their electrons. Thisformsoxide ions O²⁻and attaches in anionic bondfashionwith the positively...

L-Carnosine (β-alanyl-L-histidine) is a dipeptide of the amino acids beta-alanine and histidine. Carnosine is found throughout your body. The highest concentrations are in high energy demand areas such as your brain, heart and muscles. (Don’t mistake l-carnosine for l-carnitine). L-Carn...
The phenylpropanoids act as antioxidants by eliminating oxygen free radicals and chelating pro-oxidant metal ions, especially iron. The hydroxyl groups of these molecules confer antioxidant activity, but they are not the only factors in determining the potency of their activities. There is a single ...
The pH level refers to the hydrogen ions found in the water. It stands for ’potential of hydrogen.’ The pH level of the water at normal drinking level, carbonate, and bicarbonate are the main contributors to its alkalinity. What is Alkalinity in Drinking Water? Alkalinity is the wat...
Acids are compounds which gives away hydrogen ions when dissolved in water. Some acids are stronger than the others, for example, hydrochloric acid (HCl) is a strong acid while acetic acid (vinegar, CH3COOH) is a weak acid. Answer and Explanation:1 ...
