Laminaribiose is a chemical compound from the group of disaccharides ( double sugar ). The substance consists of two molecules of glucose that are linked by a β (1 → 3) - glycosidic bond . It arises as a partial breakdown product of laminarin from brown algae . Laminaribiosis is also found in some land plants as a component of glycosides , for example in the timeless Colchicum speciosum with the aglycon luteolin . The disaccharide was also found in honey and beer ; Barley malt contains the enzyme laminarinase ( endo -1,3 (4) -β-glucanase), which can break down β (1 → 3) - and β (1 → 4) -linked glucans in yeast .
