What are the 5 functions of proteins in biology?

Every cell in your body contains protein, so meeting your protein requirement is essential for your health.

  • Building Tissues and Muscles. Protein is necessary in building and repairing body tissues.
  • Hormone Production.
  • Enzymes.

  • Energy.

What is a role of protein in the human body?

Proteins are fundamental structural and functional elements within every cell of the body and are involved in a wide range of metabolic interactions. All cells and tissues contain protein, therefore protein is essential for growth and repair and the maintenance of good health.

What are different kinds of protein?

People use them to increase muscle mass, improve overall body composition and help meet their protein needs.

  • Whey Protein. Whey protein comes from milk.
  • Casein Protein. Like whey, casein is a protein found in milk.
  • Egg Protein.
  • Pea Protein.
  • Hemp Protein.
  • Brown Rice Protein.
  • Mixed Plant Proteins.
