*), they generally consist of 1,4-linked alpha d-galactosyluronic acid and are also known as galacturonans.
The enzyme HG methyltransferase synthesizes them from nucleoside diphosphate monosaccharides, but they can be degraded by EPGases produced by phytopathogenic bacteria and fungi. Though their primary structure depends on a glycosyl residue composition (*), they generally consist of 1,4-linked alpha d-galactosyluronic acid and are also known as galacturonans. Known for their affinity for polyamines that are present in plant cell walls, their xylo- variety is found in apple and pine pollens. FTP, name these polysaccharides found in the peels of citrus fruits which are often used in the production of jams, jellies, and gels.
