Globulin

Globulin (/ɡlɒˈbjuːlɪn/) is a group of proteins found in blood plasma. They play an essential role in the immune system and blood clotting.

Etymology

The term "globulin" is derived from the Latin word "globus," meaning "sphere" or "ball," due to the spherical shape of the protein molecules.

Types of Globulin

There are four main types of globulins, each with its own specific function:

  • Alpha Globulins: These are made in the liver and play a role in transporting lipids and fat-soluble vitamins.
  • Beta Globulins: These are also produced in the liver and help transport iron and copper in the body.
  • Gamma Globulins: These are produced by the immune system and act as antibodies to help fight infection.
  • Fibrinogen: This is a type of globulin involved in blood clotting.

Related Terms

  • Protein: A large molecule composed of one or more chains of amino acids in a specific order.
  • Plasma: The liquid component of blood, in which the blood cells are suspended.
  • Immune System: The body's defense against infectious organisms and other invaders.
  • Blood Clotting: The process by which blood changes from a liquid to a gel, forming a clot.
  • Antibody: A blood protein produced in response to and counteracting a specific antigen.
