Description

D-Galacturonan is a high-purity polysaccharide composed of galacturonic acid units, serving as a key structural component of pectin. This compound is essential for research and industrial applications requiring a defined, high-quality source of polygalacturonic acid. It is particularly valuable for scientists and manufacturers in the food science, pharmaceutical, and biotechnology sectors who require precise and consistent raw materials for product development and quality control.

Application

• Pectin Standardization & Research: Acts as a primary reference standard for analyzing and quantifying pectin content and structure in plant materials and food products.
• Enzymatic Substrate: Used as a specific substrate for studying the activity of pectinases, polygalacturonases, and other pectin-degrading enzymes in biochemical and microbiological research.
• Biomedical & Pharmaceutical Studies: Investigated for its potential in drug delivery systems, wound healing applications, and as a biocompatible material due to its polysaccharide nature.
• Food Science & Technology: Employed in research to understand and modify gelling, thickening, and stabilizing properties in food formulations.
• Cosmetic Ingredient Development: Explored for use in skincare formulations for its potential hydrating and film-forming properties.
• Agricultural & Plant Science: Used in studies related to plant cell wall integrity, fruit ripening, and pathogen resistance mechanisms.

Quality Control

Our D-Galacturonan is produced under strict quality management protocols. Each batch is tested to ensure identity, purity, and consistency, meeting the rigorous standards required for research and industrial applications. A comprehensive Certificate of Analysis (COA) detailing specific test results, including assay, moisture content, and residual solvents, is provided with every shipment to guarantee traceability and quality assurance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after each use to prevent moisture absorption, which can affect stability and handling properties.
