Biochem/physiol Actions
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.
General Description
Polygalacturonic acid sequesters metal ions and produces gels in the presence of Ca2+.
Application
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.Polygalacturonic acid can also be used for drug release or to immobilize cells or enzymes for the production of biomolecules. Polygalacturonic acid has been used in a study to assess in situ distribution and speciation of toxic copper, nickel, and zinc in hydrated roots of cowpea.
