Chemical compound

The molecule laminarin (also known as laminaran) is a storage glucan (a polysaccharide of glucose) found in brown algae. It is used as a carbohydrate food reserve in the same way that chrysolaminarin is used by phytoplankton. It is created by photosynthesis and is made up of β(1→3)-glucan with β(1→6)-linkages. It is a linear polysaccharide, with a β(1→3):β(1→6) ratio of 3:1.
