isoelectric points are just points on a molecule that represent the polarity of the molecule’s electrons. Thus, they can be thought of as the “polarity level” of a molecule. In other words, the point at which two atoms are attracted to one another. Molecules with a high isoelectric point tend to stick to one another and molecules with a low isoelectric point tend to attract each other.
That’s why we see isoelectric points on amino acids. Amino acids with a high isoelectric point are attracted to water, while amino acids with a low isoelectric point are attracted to air. The more polar a molecule is, the more ions are attracted to it, the more electrons are attracted to that molecule, the more it is an ion, the more it is an electron.
The isoelectric points on amino acids fall into two categories: basic (polar) and acidic (neutral). Both have some of the same properties, but their chemical properties are vastly different.
I know I said I want you to get a strong interest in this topic, but I’ll give it a rest. I know I’m going to get into that anyway, but if you want to know more about isoelectric points, what I mean is the different chemical properties of different molecules.
Isoelectric points are the first steps in the chemical breakdown of proteins. The proteins that make up our bodies are made up of a chain of amino acids called polypeptides. The backbone of the polypeptide is made up of a series of amino acids, each one having a specific number and the number of amino acids in a particular polypeptide chain depends on its size and shape.
If all polypeptides were made equally strong, they would be the same weight, but because some of them are shorter and some longer, they have different isoelectric points. When a polypeptide chain is folded, the amino acids are positioned at specific places that interact with one another. This allows a protein to interact with other parts of the cell so that it can perform a specialized function. That specialized function is actually the first step in the breakdown of a protein.
The first step in the breakdown of a protein is the cleavage of a bond between a small, basic amino acid and a large, acidic amino acid. These bonds are called peptide bonds. The isoelectric points of amino acids vary from one to another, so the proteins that make up your cells are constantly changing. Your body must maintain a constant level of amino acids in order to keep your cells functioning properly.
In a way, the isoelectric point is the opposite of the polarity of a particular amino acid. It refers to the degree to which one amino acid is paired with another. If a particular amino acid is paired with a proline (p), then it is positively charged. If a particular amino acid is paired with a valine (v), then it is negatively charged.
As we know, this is a key protein in the production of some vitamins. The isoelectric point is also the point at which proteins will lose their ability to form crystals. This is called denaturation.
Isoelectric point is also the name of an amino acid that is a main component of protein. It is a protein produced in the body that is used to synthesize other proteins.
