Mean ± SEM heart high-energy phosphate substrate concentration in rat pups at postnatal day 4, 8, 11, and 20 (n = 6). The heart high energy phosphate substrate levels including creatine (Cr), creatine phosphate (CrP), ATP, ADP and AMP were measured with HPLC-UV method as described by Olkowski et al. [24]. One-way ANOVA with Tukey’s post hoc test was used for the comparisons between ages and bars with the same symbol indicate no significant difference, P < 0.05. (Cr – creatine; CrP – creatine phosphate).
