Every cell in our bodies has proteins that perform a certain function. There are many types of proteins in our bodies. They include enzymes, hormones, antibodies, and blood proteins. We also have proteins that are involved in repairing damaged cells. Almost all proteins have a similar structure. This means that proteins contain the same kind of amino acids that have a linear chain attached to them.
Every protein consists of a chain of amino acids. The chain may vary in length. The length of the protein chain determines what the protein does. We may be Proteins familiar with enzymes, which are proteins that help in biochemical reactions. Enzymes play an important role in metabolism, growth and development, immunity, digestion, reproduction, and other functions.
Proteins perform a wide range of tasks in our bodies, and they are vital to our health. Almost all the proteins that form our bodies are made from 20 different amino acids. These amino acids are linked together by a peptide bond. In other words, a peptide bond connects the end of one amino acid with the beginning of the next one. There are two parts to a peptide bond.
The first part is called the α-amino group, and the second part is called the carboxyl group. The α-amino group is connected to the carboxyl group by a carbon atom.
