GO:0048217	Definition	The gel-like pectin matrix consists of the interlinked acidic and neutral pectin networks that are further crosslinked by calcium bridges. Pectins consist largely of long chains of mostly dgalacturonic acid units (typically 1,4 linkages and sometimes methyl esters). Three major pectic polysaccharides (homogalacturonan, rhamnogalacturonanI and rhamnogalacturonanII) are thought to occur in all primary cell walls.
