The importance of protein synthesis or protein in the living world is discussed.
1. As stored food: Protein acts as stored food in the body.
2. Energy production: Proteins produce energy as needed in the body. Each gram of protein in the body produces 4.10 kilocalories of energy through oxidation.
3. Body structure: Protein acts as the main structural component of the body. It forms the body of the organism.
4. Heredity: Histone proteins present in chromosomes play an important role in the inheritance of organisms.
5. Growth and Development: Growth and development of organisms are controlled by hormones. A hormone is a type of protein.
6. Transport: Proteins take part in the transport of various materials inside the cell. Hemoglobin protein transports O2 and CO2.
7. As an analgesic: Endorphin proteins produced in the brain act as pain relievers.
8. Immunity: Proteins produce antibodies in the body. Antibodies make the body immune to disease.
9. Regulation of reactions: Proteins control all types of reactions in the body.
10. Structure of Cell Membrane: Proteins form plasma membrane, nuclear membrane and membranes of various cellular organelles.
11. Prevention of viruses and cancer: A protein called interferon is used to prevent viruses and blood cancer.
