Figure 3

Backscaled first-component block loadings from the MB-PLS model of the (A) 1H NMR and (B) DI-ESI-MS data matrices. Coloring of each loading vector ranges from blue to red based on the amount of point-wise weighting applied during Pareto scaling. It is important to note that a second PLS component exists in the MB-PLS model that is not shown. Spectral contributions from citrate in the 1H NMR MB-PLS block loadings (2.6 ppm) are indicated by a bracket, and contributions from hexose and heptose in the DI-ESI-MS loadings are indicated by black squares and circles, respectively.
