Product Information

• Name: Lichenan - from Cetraria islandica
• Synonyms: Lichenin1,3:1,4-b-D-Glucan
• Brand: Biosynth
• Description: Lichenin, the poly β-D-Glucan of Cetraria islandica (Iceland moss), is found by enzymic degradation to differ in fine structure from the poly β-D-glucans of cereal grains. Thus, the basic structure of lichenin is a tetrameric unit in which two adjacent 1,4 linkages alternate with an isolated 1,3 linkage; occasionally four consecutive monomers are linked by 1,4 bonds. The immunomodulatory activity of isolichenan was tested in in vitro phagocytosis and anti-complementary assays, and proved to be active in both cases.The image was kindly provided by Prof Mike Guiry from Cork who runs ‘The Seaweed Site’.
