How are proteins obtained? What are the components of the proteins?

Answer»
  • Protein, is a macromolecule which is formed by amino acids.
  • When digestion of protein takes place, it forms different amino acids. These amino acids are transported to each cell by blood circulation.
  • By protein synthesis, these amino acids are again used to make different kinds of proteins which our body needs.
  • Animal proteins are said to be ‘first class proteins’ as they contain good quality amino acids.
  • 4 Kcal/gm energy is obtained from the proteins.
