Chrysolaminarin is a linear polymer of β(1→3) and β(1→6) linked glucose units in a ratio of 11:1.[1][2] It used to be known as leucosin.

Function

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]

Chrysolaminarin is also the major storage polysaccharide of most haptophyte algae.[5][6]
