Description

Laminaritriose is a defined oligosaccharide derived from the hydrolysis of laminarin, a β-glucan found in brown algae. This high-purity trisaccharide is a valuable biochemical tool for research into carbohydrate metabolism, enzyme specificity, and immune system modulation. It serves as a critical standard and substrate for laboratories and manufacturers in the life sciences, nutraceutical development, and plant biology sectors. Our product, CAS 3256-04-0, is supplied with guaranteed purity and batch-to-batch consistency to support your advanced applications.

Application

• Biochemical Research: Used as a defined substrate for studying the activity and kinetics of β-glucosidases, laminarinases, and other carbohydrate-active enzymes.
• Immunology Studies: Serves as a precise molecular tool for investigating the structure-activity relationship of β-glucans and their interaction with immune cell receptors like Dectin-1.
• Nutraceutical R&D: Employed as a reference standard in the development and quality control of β-glucan-based dietary supplements and functional food ingredients.
• Phytopathology & Plant Science: Used to study plant defense mechanisms, as oligosaccharide fragments like laminaritriose can act as elicitors of plant immune responses.
• Analytical Standard: Essential for HPLC, LC-MS, and other chromatographic methods as a high-purity calibration standard for quantifying laminarin-derived oligosaccharides.
• Marine Bioresource Development: A key intermediate in the valorization of brown algae, supporting research into high-value products from marine biomass.
