Description

Galactinol (Hydrate) is a naturally occurring cyclitol and key intermediate in the biosynthesis of raffinose family oligosaccharides (RFOs) in plants. This compound is of significant interest in biochemical research for its role in stress response and carbohydrate metabolism. It serves as a critical reagent and standard for laboratories and industries focused on plant physiology, functional food development, and advanced carbohydrate chemistry.

Application

• Biochemical Research Standard: Used as a high-purity reference standard in HPLC, LC-MS, and NMR for the quantification and study of galactinol and related metabolites in plant tissues.
• Plant Stress Physiology Studies: Essential for investigating the biosynthesis of raffinose family oligosaccharides (RFOs), which act as compatible solutes in plant abiotic stress tolerance (e.g., drought, salinity, cold).
• Functional Food & Nutraceutical R&D: Investigated as a potential bioactive compound or precursor for developing ingredients that modulate gut microbiota or offer prebiotic benefits.
• Enzymology & Metabolic Pathway Analysis: Serves as a specific substrate for enzymes like galactinol synthase (GolS) in studies of enzyme kinetics and pathway regulation.
• Cosmetic Science: Explored for potential moisturizing or skin-barrier enhancing properties due to its hygroscopic nature and role in plant desiccation resistance.
• Agricultural Biotechnology: Used in research aimed at genetically engineering crops for improved stress resilience by manipulating the RFO biosynthetic pathway.

Quality Control

Our Galactinol (Hydrate) is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation (NMR, IR), to ensure it meets the stringent requirements of research and development applications. A detailed Certificate of Analysis (COA) documenting purity, water content, and specific tests is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, store in a cool, dry place at 2-8°C under desiccant for long-term stability. For short-term use, storage at controlled room temperature (15-25°C) is acceptable if the container remains sealed.
