Description

Digalacturonic Acid is a specific oligosaccharide derived from the partial hydrolysis of pectin, consisting of two galacturonic acid units. This compound serves as a crucial intermediate and reference standard in the research of pectin structure, enzymatic degradation, and carbohydrate chemistry. It is primarily utilized by researchers and manufacturers in the pharmaceutical, food science, and biotechnology sectors for analytical and developmental purposes.

Application

• Biochemical Research: Used as a substrate or standard for studying pectinase, polygalacturonase, and other pectin-degrading enzymes.
• Pharmaceutical Development: Acts as a model compound for investigating drug delivery systems based on pectin and related polysaccharides.
• Food Science & Technology: Employed in research to understand pectin gelation, stability, and functional properties in food products.
• Analytical Chemistry: Serves as a high-purity calibration standard for chromatographic (HPLC, GPC) and spectroscopic analysis of pectic substances.
• Cosmetic Science: Investigated for its potential moisturizing and film-forming properties in skincare formulations.
• Plant & Agricultural Science: Used in studies related to plant cell wall structure, integrity, and pathogen interactions.
