Temperature, but not excess of glycogen, regulate post-mortem AMPK activity in muscle of steer carcasses
Post-mortem muscle temperature affects the rate of decline in pH in a linear manner from 37.5 °C down near 0 °C, and this pH decline is correlated with the enzymatic degradation of glycogen to lactate. This transformation occurs in an anaerobic context that includes the metabolic splice between glycogenolysis and glycolysis; and both processes are strongly upregulated by AMPK enzyme. In this study we reported changes (0.5 h and 24 h post-mortem) in muscle glycogen concentration, lactate anddoi:10.1101/2020.02.10.941666 fatcat:iffdztsqtbcjhpflnsf5pqx3ra
