Question

What are proteins?

Answer 1

• Chemically, protein is composed of amino acids, which are organic compounds made of carbon, hydrogen, nitrogen, oxygen or sulfur.
  
• Amino acids are the building blocks of proteins, and proteins are the building blocks of muscle mass.
  
• Thus, protein is a high molecular weight nitrogenous compound which is made up of amino acids monomers linked together by peptide linkage.
