Matrix plot of variables chemically associated with galacto-rhamnogalacturonan, e.g. galactose, galacturonic acid, rhamnose and CH100. All collected samples are included, e.g. from all sections at all time-points for both enzyme- and control-treated animals. Each point is the total mass of the given variable in the given sample. r² is the squared Pearson correlation of the two variables in each plot. CH100 carbohydrate with a molecular mass larger than 100 kDa
