Chrysolaminarin is a storage polysaccharide typically found in photosynthetic heterokonts. It is used as a carbohydrate food reserve by phytoplankton such as Bacillariophyta (similar to the use of laminarin by brown algae).[3]
Chrysolaminarin is stored inside the cells of these organisms dissolved in water and encapsuled in vacuoles whose refractive index increases with chrysolaminarin content. In addition, heterokont algae use oil as a storage compound. Besides energy reserve, oil helps the algae to control their buoyancy.[4]
