Pectin

Pectin, a bio polymer of (among other constituents) D-galacturonic acid, shown here in a powder form.

Pectin (from Ancient Greek: πηκτικός pēktikós, "congealed, curdled") is a structural heteropolysaccharide contained in the primary cell walls of terrestrial plants. It was first isolated and described in 1825 by Henri Braconnot. It is produced commercially as a white to light brown powder, mainly extracted from citrus fruits, and is used in food as a gelling agent, particularly in jams and jellies. It is also used in fillings, medicines, sweets, as a stabilizer in fruit juices and milk drinks, and as a source of dietary fiber.
