설명

일반 설명

Polygalacturonic acid is composed of galacturonic acid unit arranged as a long polymer chain. Methyl esters of polygalacturonic acid forms pectin.

애플리케이션

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

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.

생화학적/생리학적 작용

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.
