| Application: | Polygalacturonic acid has been used: • in the preabsorption of 2F4 primary antibody solution • as a substrate to determine polygalacturonase activity • in the preparation of oligogalacturonates mixture which is used as a substrate to determine the specificities of different acetylesterases |
| Application: | Polygalacturonic acid sequesters metal ions. It also produces gels in the presence of Ca2+ that can be used for drug release or to immobilize cells or enzymes for the production of biomolecules. |
| Biochem/physiol Actions: | In land plants, polygalacturonic acids are major components of cell wall polysaccharides (pectins). Bound polygalacturonase-inhibit |
| General description: | Polygalacturonic acid is composed of galacturonic acid unit arranged as a long polymer chain. Methyl esters of polygalacturonic acid forms pectin. |
