| Hazard Information | Back Directory | [General Description]
Levan is a polysaccharide produced by some microorganisms and plants. It is a non-typical biopolymer composed of fructose units linked by β-(2→6). Levan is an exopolysaccharide (synthesized outside the cell). | [Biochem/physiol Actions]
Levan has various industrial applications like cosmetics, medicine, or nanotechnology. It might exhibit anti-hyperglycemic effect and anti-tumor action, prevent diabetes-induced oxidative stress and increase catalase (CAT) and superoxide dismutase (SOD) in the heart. Levan is also recognized for its immunomodulating and prebiotic actions. |
