| 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. | | 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. |
