Description

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+.
