Biological Activity
D-Galacturonic acid hydrate has a much faster mutarotation rate than reducing sugars due to the presence of a carboxylic group, and it easily undergoes decarboxylation during thermal degradation to release carbon dioxide and generate browning precursors such as α-ketoglutaraldehyde. The decarboxylative degradation of its polymer pectin affects the quality of food during processing and storage[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Solvent & Solubility
H2O : 125 mg/mL (589.21 mM; Need ultrasonic)
DMSO : 125 mg/mL (589.21 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (sealed storage, away from moisture). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.
* Note: If you choose water as the stock solution, please dilute it to the working solution, then filter and sterilize it with a 0.22 μm filter before use.
