| Hazard Information | Back Directory | [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. |
