Definition

noun, plural: laminarins

A storage polysaccharide that is found in brown algae which is purely made up of β-D-glucose residues yields from hydrolysis.

Supplement

It is produced through photosynthesis that generates linear polysaccharides β(1→3) : β(1→6) ratio that has been catalyzed by enzyme laminarinase to break the bonds. It is used as main food storage of repeated units of glucose in many brown algae and also in phytoplankton in the form of chrysolaminarin.

Laminarin shows various health benefits like in treating diseases that are associated to theblood vessel in the heart through boosting the blood vessels in the heart thereby improving cardiovascular health. An increase amount of intake of laminarin maintains the vigorous blood vessels around the heart thus, preserving a well fit cardiovascular system.

Laminarin is a molecule from the brown seaweed Laminaria digitata. It has a molecular weight of 6 kDa and water-soluble β-glucan which able to bind Dectin-1 and block the binding of some particulate to β(1-3)-glucans like thezymosan. The action of laminarin on Dectin-1 vary on theisoform wherein cell articulating the human dectin-1b isoform does not react to laminarin while human cell dectin-1a isoform is highly reactive to laminarin.
