Identification results of potential biomarkers detected by GC/MS in liver of D-galactose group.

Metabolites which VIP>1 and p-value <0.05 have been showed in Table 1. If the value of log2 FOLD CHANGE is positive, the contect of that metabolite in D-galactose is greater than control group, If the value of log2 FOLD CHANGE is negative, the contect of that metabolite in D-galactose is less than control group.
