General description

Pectin is a polysaccharide rich in galacturonic acid and is localized to the plant cell wall. It possesses a complex structure and function.

Application

Pectin, esterified potassium salt from citrus fruit has been used:
  • in enzyme linked immunosorbent assay (ELISA)
  • in the determination of optimum pH of pectate lyase 10A (Pel10Acm) activity and in high-performance anion-exchange chromatography (HPAEC) as a part of Pel10Acm assays
  • to compare its gel properties with that of pectin extracted from sunflower head residues

Biochem/physiol Actions

Pectin is essential for plant development including growth, morphological changes and immunity. It serves as a stabilizing polymer and is useful in food and speciality products.
