Abstract

Insoluble laminarin has been partly hydrolysed by acid, and the products fractionated. Fourteen mono-, di-, and tri-saccharide products have been identified and of these, D-glucose, D-mannitol, laminaribiose, gentiobiose, 1-O-β-glucosylmannitol, laminaritriose, 3-O-gentiobiosylglucose, 6-O-β-laminaribiosylglucose, and 1-O-β-laminaribiosylmannitol are considered to be true structural fragments of laminarin. It is suggested that the laminarin molecules may consist of unbranched chains of β-1:3-linked glucose units, occasionally interrupted by β-1:6-links, and that some, but not all, of the chains are terminated by mannitol. Soluble laminarin probably has a similar structure but contains a higher proportion of mannitol and of β-1:6-links. A method for the quantitative determination of mannitol in laminarin is described.
