Description

Rhamnogalacturonan As3 is a specific, high-purity polysaccharide derived from pectin, characterized by its unique rhamnogalacturonan I (RG-I) backbone structure. This compound is valued for its functional properties as a bioactive polymer and a structural component in advanced material science. It is essential for researchers and manufacturers in the pharmaceutical, nutraceutical, cosmetic, and food technology sectors who require precise, high-quality biomaterials for product development and formulation.

Application

• Pharmaceutical Research: Used as an excipient or active ingredient in drug delivery systems, particularly for colon-targeted formulations due to its fermentability by colonic microflora.
• Nutraceuticals & Functional Foods: Incorporated as a prebiotic fiber and bioactive ingredient to support gut health and modulate immune function.
• Cosmetic Science: Serves as a natural, film-forming agent, moisturizer, and texture enhancer in skincare and haircare formulations.
• Biomedical Materials: Investigated for use in hydrogels, wound dressings, and tissue engineering scaffolds due to its biocompatibility and gelling properties.
• Food Science: Acts as a natural thickener, stabilizer, and emulsifier in specialty food products, improving texture and mouthfeel.
• Agricultural Technology: Explored as a component in biostimulants and seed coatings to enhance plant growth and stress resistance.
• Analytical Standards: Serves as a certified reference material (CRM) for the quantification and characterization of pectin-derived polysaccharides in quality control laboratories.
