Lipomannan is a mycobacterium immune agonist. In addition, it is a major constituent of the mycobacterium cell wall. This gycloconjugate is a virulence factor that plays a key role in the human immune system via interaction with various immune cells. It is also considered to be a precursor of lipoarabinomannans.
