Examples of Proteins

We can define Proteins as the structural blocks of the cellular system and are formed by joining of  amino acids by peptide bonds (polymerization) .Proteins mainly consists of  Carbon,Hydrogen,Nitrogen,Oxygen.  Sulphur  and Phosphorous may also be present in certain  proteins.In this post we will learn about proteins, examples of proteins and their properties.

We have three types of proteins:

1) Simple Protein

2) Conjugated Protein

3) Derived Protein

Simple proteins are usually classified according to their solubilities and coagulabilities.Simple Proteins are soluble in polar solvents like water.  

Conjugated proteins, these are complexes of simple proteins (apo proteins ) and a non protein part (prosthetic group) and the entire molecule is called a holoprotein.Conjugated proteins are classified according  to the  prosthetic group. 

The derived proteins are produced due to chemical reactions of native proteins with different substances like water, acids, alkali,heat, radiation etc.

In the future posts, we will learn what is the function of proteins, and the role it plays in day to day life.
