List of Proteins

A protein is a complex molecule composed of amino acids that plays a crucial role in various biological processes. The following is a list of notable proteins:

Hemoglobin

Hemoglobin is a protein found in red blood cells that is responsible for transporting oxygen from the lungs to the rest of the body.

Insulin

Insulin is a protein hormone that regulates blood sugar levels by facilitating the uptake of glucose into cells.

Collagen

Collagen is a structural protein that provides strength and elasticity to tissues such as skin, tendons, and bones.

Myosin

Myosin is a protein involved in muscle contraction and movement.

Immunoglobulins

Immunoglobulins, also known as antibodies, are proteins produced by the immune system to help defend the body against pathogens.

Enzymes

Enzymes are proteins that catalyze biochemical reactions in the body, speeding up the rate of these reactions.

Keratin

Keratin is a protein that forms the structural basis of hair, nails, and the outer layer of skin.

Actin

Actin is a protein that plays a key role in cell structure and movement.

Casein

Casein is a protein found in milk that is used in the production of cheese and other dairy products.

Ferritin

Ferritin is a protein that stores and releases iron in the body, helping to maintain iron balance.
