Glomalin is a glycoprotein that is mainly formed on hyphae and spores of arbuscular mycorrhizal fungi in the soil and in roots. Glomalin is believed to be a homolog of the heat shock protein Hsp60 .
As a glycoprotein, Glomalin stores carbon in the form of proteins and carbohydrates (especially glucose ). It permeates organic matter , which is bound to sand , silt and clay . Glomalin contains about 30 to 40% carbon and single-digit percentages of nitrogen and hydrogen. It forms small clumps of earth. This granulate loosens the soil and binds carbon in the soil. It also increases the air permeability and water retention of the soil.
