Pectic polysaccharide (beta 1,4-galactan)

Pectic polysaccharide (beta 1,4-galactan); Pectic polysaccharide; beta 1,4-galactan

The plant cell wall surrounds the plant cell as a complex network of polysaccharides classed as: cellulose, hemicelluloses and pectic polysaccharides and glycoproteins. Anchored to or embedded into plant cell wall are other polymers, like: lignin, suberin or cutin. Homogalacturonan is a pectic polysaccharide of alpha-1,4 linked galacturonic acid residues. Pectin contains a complex set of polysaccharides that can be found in many primary cell walls.
