Explain about the Proteins?

The term protein (Greek: proleuo- to occupy first place) was first suggested by Berzelius to describe the complex organic nitrogenous substances found in animal and plant tissues. Proteins form three-fourths of the animal body on a moisture-free basis. They are essential for life processes. All the basic functions of life depend on proteins. Indeed, no form of life exists without proteins. They are found in every cell, make up the contractile elements and enzymes that catalyze the release of energy for the maintenance of life and there is no physiological function in which they do not participate. Now in this unit let us get familiarized with the chemical nature, digestion, absorption, utilization and other nutritional aspects of proteins.
