Protein Role in 5 Blood Functions


Do you know that the use of proteinProtein Guide: 5 Finest Writings Collected Protein Guide: 5 Finest Writings Collected is not contracted till growth, formation, and development; it is also an active contributor to the functions of blood cells like protection, transportation, and regulation.

Know below how protein helps blood cells in vessels and what are those major 5 blood functions in which the participation of proteins can't be ignored.

Formation of Blood Cells and Transportation of Oxygen

Protein helps in the formation and functioning of our blood cells. The red blood cells (RBCs) take oxygen to the lungs or gills and release the oxygen molecules in tissues. The flexibility, deformability, and durability of these red blood cells depend on proteins. The membranes of these cells are made of lipids and proteins.

The transportation responsibility of 98% of oxygen remains on red blood cell protein.

Rest 2% of oxygen gets dissolved in blood plasma; so it is carried by them.

3 Types of proteins that Help Blood Cells in Transport

Importantly, there are three types of proteins in plasma that play an important role in transportation.

  1. Albumins Protein helps many substances in binding with plasma and dissolving. This way, proteins play a vital role in the plasma transportation of hormones, drugs, and fatty acids.
  2. Globulins Protein helps in lipid transport. They carry fats to various cells so that the fat can be used for:
    • Hormonal functions
    • Manufacturing of steroid hormones
    • Energy metabolism
    • Making of cell membranes
    • Reconstruction of the membrane.

    They do not let cholesterol invade and settle in the arteries walls. But they favor the cholesterol deposition in arterial walls too and so play a vital role in cholesterol regulation and diseases related to heart and blood vessels.

  3. Fibrinogen Proteins help in the framework formation of the blood clots, playing a key role in blood coagulation.

Protein Use in pH Balance

Proteins help in maintaining a stable pH and keep the blood little basic. For this process, proteins behave as weak bases and bind with those H+ ions which are in excess. This way they remove extra H+ from blood, keeping them slightly basic.


The blood cell contains some protein on its surface too. Other than clotting and transport, proteins play their role in defense as well.

Distribution of Water

Plasma proteins also manage the water distribution between blood cells and tissues.

Role of Protein in Clotting

Though plasma is mainly made of water, yet it also contains different proteins. The moment blood spills, plasma protein starts its work and clumps with some cells, making a clot. The plasma proteins cause blood coagulation by their specific ways of interactions. Thus, protein helps the body to respond while injuries and aids in controlling blood loss and protecting from viruses.

If you are ignoring protein taking it as a nutrient that is important for bodybuilders only, change your perception as this is a vital element of any nutritious diet.
