Alternations in dipeptide amounts in T. vaginalis cultured in different iron concentrations. The relative levels of identified dipeptides are listed in this chart. A total of 170 dipeptides were identified in this work. Dipeptides without significant differences are labeled with ◎. Dipeptides accumulated in IR cells are labeled with black-filled square, while dipeptides accumulated in ID cells are labeled with black-filled circle (P < 0.05)
