Answer;
Amino acid side chains have many carboxyl and amino groups.
Explanation;
-A buffer solution is a solution that resists changes in pH when small quantities of an acid or an alkali are added to it. It is a chemical substance that helps maintain a relatively constant pH in a solution, even in the face of addition of acids or bases.
-Buffering is important in living systems as a means of maintaining a fairly constant internal environment, also known as homeostasis.Small molecules such as bicarbonate and phosphate provide buffering capacity as do other substances, such as hemoglobin and other proteins.
-
Protein buffer systems depend upon proteins, as opposed to nonprotein molecules, to act as buffers and consume small amounts of acid or base. Since amino acids have the capability of reacting with both acid and base, they naturally act as buffers.
Structure of Water and Hydrogen Bonding
- living systems depend on water and its polarity as well as hydrogen bonds
- hydrogen bonds result in the cohesion: ability for water molecules to stick together through hydrogen bonds, adhesion: ability for polar part of water to stick to other polar surfaces and surface tension: water's attraction to each other in bonds rather than air so have tension on surface
- cohesion of water is the Attraction between molecules of the same substance.
- Hydrogen bonds between the oxygen of one water molecule and a hydrogen of another water molecule.
- Adhesion of water is the property of water to attract with other substance.
