The Dipeptides Ile-Tyr and Ser-Tyr Exert Distinct Effects on Catecholamine Metabolism in the Mouse Brainstem

Figure 2

Effects of dipeptide ingestion on NA and MHPG levels in the brainstem. NA (a) and MHPG (b) concentrations in the brainstem were determined 30 min after oral ingestion of dipeptides or Tyr alone. Data are expressed as mean ± SEM ( for Tyr-, IY-, and YP-groups; for SY-group). Comparisons between Tyr- and dipeptide-groups were analyzed using one-way ANOVA followed by Tukey-Kramer’s test for post hoc analysis. .
