  • Storage Proteins – they keep the reserve amino acids until such time the body is ready to use this reserves.
  • Transport Proteins – the carrier of proteins.

According to an article from Healthline, here are the key roles of proteins:

  • for growth and maintenance of body tissues
  • for biochemical reactions to take place
  • for bodily functions such as digestion, energy production, blood clotting, and muscle contraction
  • for transporting chemical functions between cells, tissues, and organs
  • for the stiffness and rigidity of the cells like keratin (for the hair, nails, and skin), collagen (for bones, tendons, ligaments, and skin), elastin (to allow tissues contract and stretch and still return to its original shape)
  • for the regulation of acids and bases of body fluids
  • for maintaining good immunity
  • for transporting and storing nutrients for the body
  • for supplying the body with energy
