Description

(1-3)-α-Mannan is a high-purity polysaccharide derived from natural sources, characterized by its specific α-1,3 glycosidic linkages. This unique structural configuration is critical for its bioactivity and functional properties in advanced industrial and research applications. It serves as an essential raw material and functional ingredient for manufacturers in the pharmaceutical, nutraceutical, cosmetic, and life science research sectors seeking consistent quality and reliable supply.

Application

• Immunological Research & Adjuvant Development: Used as a model compound and active component in studying immune modulation, vaccine adjuvants, and macrophage activation due to its interaction with specific receptors.
• Pharmaceutical Excipients: Employed as a functional carrier, stabilizer, or controlled-release matrix in solid dosage forms and novel drug delivery systems.
• Nutraceutical & Dietary Supplements: Incorporated into formulations for gut health and prebiotic applications, leveraging its potential to modulate microbiota.
• Cosmetic & Personal Care: Acts as a natural moisturizing agent, film-former, and texture enhancer in skincare and haircare products for improved hydration and feel.
• Biochemical Reagent: Serves as a standard or substrate in enzymatic assays (e.g., for mannanase activity) and carbohydrate chemistry research.
• Microbiological Media & Fermentation: Used as a selective carbon source in culture media for the growth and study of specific microbial strains.
