Plant cell walls are composites that consist of polysaccharides, proteins and, if they are secondary cell walls, lignin as well as a number of minor constituents. The major components are the polysaccharides and, owing to their complexity, they are usually subdivided into cellulose and others, namely the noncellulosic polysaccharides. These noncellulosic polysaccharides encompass pectins (d-galacturonans) and hemicelluloses (d-xylans, d-glucans, d-mannans, etc.) and each has its own specific function and responsibility within a particular type of cell wall.
