POLYGALACTURONIC ACID Usage And Synthesis

Uses

Polygalacturonic Acid is found in ripe fruits and some vegetables and is a degradation product of pectin in plants.

Uses

Polygalacturonic acid may be used to identify, differentiate and characterize plant cell wall degrading polygalacturonase(s) from fungi.

Definition

ChEBI: D-galactopyranuronic acid is the pyranose form of D-galacturonic acid It is a conjugate acid of a D-galactopyranuronate.

General Description

Polygalacturonic acid is composed of galacturonic acid unit arranged as a long polymer chain. Methyl esters of polygalacturonic acid forms pectin.

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.
