| | LEVAN Usage And Synthesis |
| Uses | Levan - from Serratia Levanicum is an agent for prevention or remediation of dementia and compound containing same. | | Uses | Levan is a fructose derivative, it is moisturizing and anti-inflammatory, it is also used to help improve skin barrier function.
| | Uses | Levan from Erwinia herbicola has been used as a:
- standard for the nuclear magnetic resonance (NMR) spectroscopy analysis of levan produced by Bacillus licheniformis NS032 in sugar beet molasses-based medium
- polysaccharide substrate to test the ability of Prevotella copri isolates to grow when polysaccharides were provided as the sole carbon source in vitro
- substrate in levanase activity assay
| | 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. |
