We often notice so many bodybuilders and several physical trainers drinking whey protein along with milk for building up their metabolism and strength. However, when it comes to our body, our hair and nails are made of proteins mostly. Basically, proteins are the fundamental building blocks of the human body. They are large and complex macromolecules, also called bio-molecules that perform a huge role in the functioning and regulating of the body cells, tissues and several other organs in our body. They are also used to provide strength to our body for producing hormones, enzymes, and many other metabolic chemicals. They are also involved in the functioning and the regulation of all our body cells, tissues and organs. Proteins are composed of amino acids that are arranged into several different groups. These fundamental amino acids sequences are known to be specific and all its arrangements are controlled by the human DNA. Since our body is not able to synthesize these essential amino acids by its own, it is essential for us to have plenty of protein foods in our daily diet to keep the metabolisms of our body stable. We will learn about the simple definition of protein, type of protein and its function, the difference between globular and fibrous protein, and the classes of proteins in detail in this article.
The classification of proteins is done on the basis of their shape, constitution and the nature of their molecules. Hence, the different classes of proteins are as follows:
The role of protein in the human body is as follows: Structural Functions: Proteins are called the building blocks of our body. They make for an essential component of several structures in the cells and the tissues. You can also find these proteins in the outer membrane of all the cells that are present in the human body. You can also find the structural proteins in your hair, skin, and muscles. Proteins generally act to strengthen all these structures. Proteins working together would allow movement within the body, for example, the contraction of muscles and the movement of food through your digestive system, etc. These proteins are required for the growth, development, repair and healing of the tissues.
Since there are different rearrangements of amino acids, the structure of the proteins is divided into four different types:
There are 20 different amino acids in the proteins which make up each molecule of protein, and these amino acids are therefore split into 2 categories named non-essential amino acids and essential amino acids. Therefore, the two types of protein in the body are non-essential amino acids and essential amino acids.
Haemoglobin is a kind of conjugated protein. It contains a basic protein called globin which is joined to a non-protein group heme, therefore, the name haemoglobin. The haemoglobin molecule is a complex of 4 different heme molecules that are joined with 4 globin molecules. The name haemoglobin is derived from the two words heme and globin, which reflects the fact that each of the subunits of haemoglobin is a globular protein having an embedded heme group. Each of the heme group consists of one iron atom, which can bind to one oxygen molecule with the help of the ion-induced dipole forces. Hence, haemoglobin is a type of protein called globin.
