What is POLYGALACTURONIC ACID?
The Uses of POLYGALACTURONIC ACID
Polygalacturonic Acid is found in ripe fruits and some vegetables and is a degradation product of pectin in plants.
The Uses of POLYGALACTURONIC ACID
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.
What are the applications of Application
Polygalacturonic acid is a reagent which sequesters metal ions and produces gels that can be used for the production of biomolecules
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.
