12672-40-1O=C(O)[C@H]1O[C@H](O)[C@H](O)[C@@H](O)[C@H]1OAEMOLEFTQBMNLQ-BKBMJHBISA-NPectin is a heteropolysaccharide containing a large proportion of D-galactopyranosyluronic acid residues in alpha-(14) linkage, of which the hydroxy groups at positions C2 and C3 may be acetylated and carboxy groups at positions C6 may be esterified to varying degrees by methyl groups or be partially or completely converted into salts. It has a role as an antidiarrhoeal drug, a food emulsifier, a Saccharomyces cerevisiae metabolite, a plant metabolite, a food stabiliser, a food thickening agent and a food gelling agent. It is functionally related to a homogalacturonan.
