Amino acids are the building blocks of proteins. Each amino acid is composed of a monomer, and these monomers join together to form a complex molecule called polypeptides.
 For example, hemoglobin is an oxygen-carrying protein in the red blood cells. It is a globular protein and is made up of two polypeptide sub units. It consists of two alpha and two bets chains. 
Proteins are rich energy units and there are different sources of proteins such as beans, pulses, seeds, nuts, milk, and yogurt, etc.
