Chrysolaminarin (leucosine) is an algae from the group of stramenopiles such. B. Diatoms and in the calcareous algae (Haptophyta) occurring reserve material that is used as an energy reserve. Chrysolaminarin consists of chain-like, unbranched, interconnected glucose molecules , so it is a carbohydrate ( polysaccharide ). While in the starch of green plants and red algae the glucose is α1 → 4- and α1 → 6-glycosidically linked, the chrysolaminarin consists of β1 → 3- and β1 → 6-glycosidically linked D- glucose with a ratio of 11: 1.
