1Refer to Supplementary Table S1 for full list of metabolites, ∗fold change = 2.0 represents an increase in metabolite concentration, while lower values (anything below FC = 1) represents decrease. An increase of FC = 2 is equivalent to a decrease of FC = 0.5 [on both sides of (0, 0)] on the graph. The metabolites of FC < 0.5 indicate the depleted metabolites and are considered here.
