The importance of protein

The term protein derives from the Greek prote or primary.

The importance of proteins in living organism embraces two aspects: structural and functional. Proteins are the chief organic constituents of muscles and other tissues.

Many proteins are enzymes that catalyze biochemical reactions and are vital to metabolism.

Proteins are parts of the intracellular and intercellular structure of animals. The importance of dietary protein for the maintenance of the immune systems has also been suggested, with the dietary protein influencing the human response to infection though several mechanisms: gut barrier functions and general immune-competence.

Proteins are the molecular machines that drive and control virtually all of the features of biological organisms at the molecular levels.

The primary function of DNA and the gens contained therein is to store the instructions for creating proteins.

Proteins are required by humans for growth (protein synthesis) and for repair and maintenance of cells. Since mature adults have, in essence, ceased to grow, their protein requirement is less, per unit weight, than that of those who are still growing.

Proteins are also central in cell signaling, cell adhesion and cell division for growth and reproduction.
