Polygalacturonic acid (de la pectine) ≥86%, en poudre
Polygalacturonic acid
Polygalacturonic acid is a water insoluble, transparent gelatinous acid existing in ripe fruit and some vegetables. It is a product of pectin degradation in plants, is produced via the interaction between pectinase and pectin.
Polygalacturonic acid sequesters metal ions. It also produces gels in the presence of Ca2+ that can be used for drug release or to immobilize cells or enzymes for the production of biomolecules.
In land plants, polygalacturonic acids are major components of cell wall polysaccharides (pectins). Bound polygalacturonase-inhibiting peptides (PGIP) protect pectin from degradation by fungal polygalacturonases.
Soluble in 0.1 N HCI (50 mg/2 ml-clear, colorless solution); insoluble in water and ethanol.
