20 Examples of Proteins

Hemoglobin, Insulin, Collagen, Enzymes, Antibodies, Keratin, Myosin, Actin, Immunoglobulins, and Albumin are few examples of Proteins.

Examples of Protiens

Here are few examples of protiens:

1. Alpha-Actin

Alpha-actin is an example of protein that is found in muscle tissues. It is involved in muscle contraction and cell structure.

2. Hemoglobin

Hemoglobin is a protein in red blood cells that binds to oxygen and carries it throughout the body. It also facilitates oxygen transport.

3. Collagen

Collagen is an example of structural protein, that is found in skin, bones, and connective tissues, providing strength and elasticity.

4. Insulin

Insulin is a hormone produced by the pancreas, regulating blood sugar levels by facilitating glucose uptake by cells.

5. Myosin

Myosin is a motor protein involved in muscle contraction and cellular movement.

6. Albumin

Albumin is a protein in blood plasma that helps maintain osmotic pressure and transports various substances.

7. Keratin

Keratin is an example of fibrous protein found in hair, nails, and the outer layer of skin, providing strength and protection.

8. Enzyme

Enzymes are a diverse group of proteins that catalyze biochemical reactions in cells.

9. Immunoglobulin (IgG)

Immunoglobulins, or antibodies, are proteins produced by the immune system to defend against pathogens.

10. Creatine Kinase

Creatine kinase is an enzyme that plays a role in energy metabolism, particularly in muscle cells.

11. Fibrinogen

Fibrinogen is a blood clotting protein that converts to fibrin, forming blood clots to stop bleeding.

12. Caspase

Caspases are enzymes involved in programmed cell death (apoptosis).

13. ATP Synthase

ATP synthase is a complex protein that generates adenosine triphosphate (ATP) in cellular respiration.

14. Cytochrome C

Cytochrome c is a protein in the electron transport chain, facilitating the production of ATP in mitochondria.

15. Neurotransmitter Receptor

Various proteins in the nervous system serve as receptors for neurotransmitters, facilitating neural signaling.

16. Growth Hormone

Growth hormone is a peptide hormone that stimulates growth and cell reproduction.

17. Interferon

Interferons are proteins that help the immune system respond to viral infections.

18. Lipoprotein

Lipoproteins transport lipids (fats) in the bloodstream, including low-density lipoprotein (LDL) and high-density lipoprotein (HDL).

19. Transferrin

Transferrin is a blood plasma protein responsible for transporting iron throughout the body.

20. Collagenase

Collagenase is an enzyme that breaks down collagen in tissues, often used in wound healing and tissue engineering.
