Proteins are the essential biomolecules, consisting of one or more long chains of amino acid residues. They are large macromolecules, which play a vital role in growth and development, therefore it is called as the building blocks of the body. They are the class of biologically important compounds with high molecular weight.
Proteins are perhaps the most complex organic materials produced in nature. Plants build up their proteins from carbon dioxide, water, and minerals in the presence of sunlight, whereas animals derive it from eating plants.
Among various types of proteins, Albumin and globulin are the two different types of protein present in our blood cells, and they play an important role in :
