Structural description

Laminaran (or laminarin) is a storage polysaccharide of Laminaria sp and other brown algae such as Fucus vesiculosus, Saccharina longicruris and Ascophyllum nodosum. It is a linear polysaccharide made up of β(1-3) glucan with some β(1-6) branch point.

The majority of laminarans contain polymeric chains of two types: one type is built only of Glcp residues (G-chains), whereas the other type is terminated with 1-O-substituted D-mannitol residues (M-chains).

Activities and Uses

Laminaran is claimed to modulate immune responses in mammals. Sulfated laminaran has been shown to have heparin-like properties and to be an elicitor of plant defense reactions against viral infections. Laminaran also has dietary fiber properties.
