This product is not tested for molecular weight. However, a publication cites a peak molecular weight of 250 kilodaltons (250,000) as determined by gel permeation chromatography (GPC). No information on the molecular weight distribution was reported, only the peak molecular weight.

General description
Sodium polypectate sequesters metal ions and, in fungal cultures, it is used as a carbon source and inducer of polygalacturonases.
Application
Sodium polypectate can be used to sequester metal ions. In fungal cultures, it is used as a carbon source and inducer of polygalacturonases.Polygalacturonic acid has been used in a study to assess an alkaline-active and alkali-stable pectate lyase from Streptomyces sp. S27 with potential in the textile industry. It has also been used in a study that investigated optimization of production and reaction conditions of polygalacturonase from Byssochlamys fulva.
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.
