Merck, L9634-500MG, Laminarin from Laminaria digitata

General description
Substrate for laminarinase.
The fronds of Laminaria and Saccharina species contain laminarin, a low molecular weight storage glucan. It is localized to the vacuoles. Laminarin structure contains β-(1,6)-intrachain linked (1,3)-β-d-glucan.
Application
Laminarin from Laminaria digitata has been used:
as a stimulant to study its effect on the respiratory burst using haemocytes of P. vannamei
as a carbon source to study its effect on enzyme production using Pichia membranifaciens culture
as a carbon source for Polaribacter sp. culture

Biochem/physiol Actions
Laminarin is a polysaccharide of glucose found in brown algae and utilized as a food reserve.
Laminarin is a biologically active compound effective against inflammation. It serves as an antioxidant and anticoagulant. Laminarin also inhibits apoptosis and tumor development. It acts as a predominant source of carbon among aquatic prokaryotes.
Other Notes
Polysaccharide; primarily poly(β-Glc-[1→3]) with some β-(1→6) interstrand linkages and branch points.
