Polygalacturonic acid

25990-10-7; Galacturonic acid polymer

Polygalacturonic acid is a polysaccharide where the monomeric unit is D-galacturonic acid, a sugar acid. This polymer forms the main structural backbone of pectin, a complex polysaccharide found in the cell walls of terrestrial plants. Its polymeric structure and ability to form gels in the presence of sugar and acid make it a crucial component in the food industry for products like jams and jellies.
