The phosphorylation of pAMPKα and pACC. (A) Representative immunoblots showing phospho-AMPKα (upper), phosphor-ACC (lower), and ACC on L6 cell. Dose-dependent black vinegar enhances the phosphorylation of AMPKα and ACC. Met, metformin. (B) Ratio of phosphorylation was quantified against ACC, and AMPKα
