Laminaribiose is a chemical compound from the group of disaccharides ( double sugars ). The substance consists of two glucose molecules, which are linked via a β ( 1 → 3) -glycosidic bond. It arises as a partial degradation product of laminarin from brown algae. Also, in some land plants, we find the laminaribiose as part of glycosides, such as in the Colchicum speciosum Timeless with the aglycone luteolin. Furthermore, the disaccharide was found in honey and beer; Barley contains the enzyme laminarinase ( endo -1, 3 (4 ) - β -glucanase ) that β (1 → 3) - can disassemble, and β (1 → 4 )-linked glucans of the yeast.
