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.
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
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.
