Biological Activity
D-Galacturonic acid 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 : 100 mg/mL (515.09 mM; Need ultrasonic)
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.
