pectin

(Science: protein) class of plant cell wall polysaccharide, soluble in hot aqueous solutions of chelating agents or in hot dilute acid. Includes polysaccharides rich in galacturonic acid, rhamnose, arabinose and galactose, for example the polygalacturonans, rhamnogalacturonans and some arabinans, galactans and arabinogalactans.
