Alpha-1-acid glycoprotein (AGP) is a simplified name for orosomucoid (ORM). ORM is an acute phase (Acute phase protein) plasma alpha-globulin glycoprotein and is modulated by two polymorphic genes. It is synthesized primarily in hepatocytes and has a normal plasma concentration between 0.6-1.2 mg/mL (1-3% plasma protein).Plasma levels are affected by pregnancy, certain drugs, and certain diseases, particularly HIV. The only established function of ORM is to act as a carrier of basic and neutrally charged lipophilic compounds. In medicine, it is known as the primary carrier of basic drugs (whereas albumin carries acidic drugs), steroids, and protease inhibitors.Orosomucoid increases in amount in obstructive jaundices while diminishes in hepatocellular jaundice and in intestinal infections.
