Description

Laminaripentaose is a defined oligosaccharide composed of five glucose units linked by β-(1→3) glycosidic bonds. This specific molecular structure makes it a valuable biochemical tool for research into plant and microbial cell wall biology and enzymatic processes. It serves as a critical substrate and standard for studying β-1,3-glucanases, laminarinases, and related carbohydrate-active enzymes. Industries and research institutions focused on enzymology, carbohydrate chemistry, and plant pathology will find this high-purity compound essential for their work.

Application

• As a specific substrate for the assay and characterization of endo- and exo-β-1,3-glucanases (laminarinases).
• Used as a biochemical standard in chromatography (HPLC, HPAEC-PAD) for the analysis of β-glucan oligosaccharides.
• Research into plant defense signaling pathways, as oligosaccharides can act as elicitors.
• Studies of microbial metabolism, particularly in fungi and bacteria that degrade laminarin.
• Investigations of carbohydrate-protein interactions and receptor binding studies.
• Enzymatic synthesis of higher molecular weight β-glucans or defined glycoconjugates.
