The corresponding loading plot of LV-2 is displayed in Figure S5. Computer had a strong unfavorable contribution on the second PLS element (LV-2) meaning that Computer levels are elevated in batch b (red symbols in Figure 4). For this reason batch difference, Cho, lipid, and Pc had been excluded from additional consideration of resistance characteristics. PCA and oPLS discriminant analysis (oPLS-DA) was additionally performed only on the samples with the same batch (Figure S6 shows this for batch a, related results were obtained for batch b) and confirmed that GSH, Tau, AXP, and Lac would be the most important contributors to distinguishing samples determined by resistance, whereas Pc had little, or no impact on separation as outlined by resistance (Figure S6 bottom).Molecules 2021, 26, 6766 Molecules 2021, 26, x FOR PEER REVIEW7 of 15 7 of0.3 GSH 0.2 GSH 0.1 AXP AXP NA UTP 0 Ura Hxn, NAD Ino/ Ade Ino/ Cyd Ura Ino/ Cyd, Urd Ade Ade Ino Ino/ Ade Computer Computer -0.2 Cre Cho Cho Gly GSH GSH Lac Lac UDPNAcGlc, UDPNAcGal GPC GPC Tau Tau GSH Tau Tau Tau Cys Asn Tau Tyr GSH Pro Phe la Met Cit Glu Val Glu Met Ala GSH, la GSH Lac, Lip ( H2)n LipLV 1 (Component) (20.94 )GSHLip ( H3)Ile-0.-0.Cre PC-0.150 Frequency BucketsFigure 5.
