Description

Pentagalacturonic Acid is a defined oligosaccharide derived from the hydrolysis of pectin, representing a specific chain length of galacturonic acid units. This high-purity reference standard is critical for research and analytical applications requiring precise molecular characterization. It is primarily utilized by scientists and quality control laboratories in the food science, pharmaceutical, and biotechnology sectors for method development, calibration, and structural studies of pectin and related polysaccharides.

Application

• Analytical Reference Standard: Used as a primary standard in HPLC, GPC, and other chromatographic methods for the quantification and characterization of pectin degradation products.
• Enzyme Substrate & Research: Serves as a specific substrate for studying the activity, kinetics, and inhibition of pectinolytic enzymes such as polygalacturonase and pectin lyase.
• Food Science & Technology: Employed in research to understand pectin structure-function relationships, gelation mechanisms, and the impact of processing on pectin quality.
• Biomedical Research: Investigated for its potential bioactive properties, including prebiotic effects and interactions with biological systems, due to its defined oligomeric structure.
• Quality Control (QC): Essential for the internal QC of pectin manufacturers and suppliers to ensure batch-to-batch consistency and purity of products.
• Academic Research: A key tool in carbohydrate chemistry and plant biochemistry laboratories for teaching and fundamental research on cell wall polysaccharides.
