CAS No.: 25249-06-3

Molecular Formula: (C₆H₈O₆)n

Specification: Polygalacturonic Acid is typically available as a white to off-white powder, derived from pectin through enzymatic or chemical hydrolysis, supplied in high-purity forms (85% or greater) with varying molecular weights for research or industrial use.

Appearance and Color: white to off-white powder

Ingredient Information: Polygalacturonic Acid is a polysaccharide composed of repeating galacturonic acid units linked by α-1,4-glycosidic bonds, extracted from plant cell walls (e.g., citrus peels or apple pomace), often purified without significant additives beyond processing aids.

Uses: Polygalacturonic Acid is widely used as a model compound in enzyme studies (e.g., pectinase activity), a gelling agent or stabilizer in food applications, and a substrate in biochemical research; it is also explored for its potential prebiotic and antimicrobial properties.
