What is a polypeptide?
proteins are made of building blocks called amino acids. When two or more amino acids are held together in the chain, they can be called polypeptide. Every connection between amino acids, where the energy attraction holds the blocks together, is a peptide bond. Polypeptides perform many functions in the body.
amino acids are small molecules that are basic building blocks in biology. Many biological functions rely on protein or polypeptide. In general, very short polypeptides are usually called peptides and very long, with more than about 100 amino acids, are called proteins. All proteins fall into the polypeptide group, but some polypeptides do not correspond to the criteria as a protein.
Peptide part of the name comes from the type of bond between two amino acid blocks. Each amino acid has one end called the alpha-carboxyl group and another end called the alpha-amino group. These two groups have different chemical properties.
Alpha-Karboxyl has a tendency to join the connectionIT with alpha-amino and vice versa. Therefore, the only amino acid tends to be attached to another amino acid in a specific way, such as one person holding hands with another person. One uses his right hand and the other uses her left hand to complete the bond. This form of binding is a peptide bond, and when both molecules hold together, they produce one molecule.
The duration of two amino acids requires energy. The body provides this energy when it needs to produce new polypeptides for biological use. After the two amino acids are stuck together, the binding is relatively stable and easily disintegrates.
polypeptides contain many of these amino acids stuck together in a straight line, in the same way as many people holding their hands between them. Usually, the polypeptide chain also has chains that suffer from the side at certain points. One polypeptide can contain up to 2,000 individualsMino acid.
In the body, polypeptides can perform functions as they are. Perhaps they will also have to connect with another to create a new protein with a biological function. Sometimes a single polypeptide is created as a large cell product and the cell then uses an enzyme to chop it into functional parts.
polypeptides are first performed when the cell reads its genetic instructions and converts this information into an amino acid sequence. Each gene code for a particular product and necessary amino acids are collected and sticks together in the correct order. The sequence is essential for the polypeptide to work properly, because otherwise it cannot interact with its goals properly.
