Oligosaccharide metabolism in Trichomonas vaginalis cultured under different iron concentrations. The levels of oligosaccharides detected in this analysis are shown in bar charts. Significantly regulated compounds are shown in red (P < 0.05). The corresponding enzymes are listed by the arrows, and relative RNA expression levels (ID/IR) are indicated. Genes upregulated in ID cells are shown in red, while genes downregulated in ID cells are shown in green [5]. The gray compounds represented not being detectable in this analysis. Galactinol synthase is lacking in T. vaginalis
