Xylogalacturonan is a substituted homogalacturonan in which the α-1,4-linked D-galacturonate backbone is substituted at position O-3 with a β-D-xylopyranose. Occasionally the xylose is further substituted at position O-4 with an additional β linked xylose.
The homogalacturonan backbone is partially methylesterified at the C-6 carboxyl, and may be O-acetylated at positions O-2 or O-3.
