چکیده انگلیسی
The aim of this study was to investigate the effects of protein S-nitrosylation on the glycogen metabolism in postmortem pork. The pork samples were incubated with control (0.9% NaCl), nitric oxide synthase (NOS) inhibitor, or NO donor for 4 and 12â¯h at 4â¯Â°C. Results indicate that NOS inhibitor treatment led to significantly lower level of glycogen and higher lactate content at 24â¯h compared those of control and NO donor treatments (Pâ¯<â¯0.05). The pH of NOS inhibitor treatment was significantly lower than other treatments, which indicates the fast glycolysis during postmortem aging (Pâ¯<â¯0.05). In addition, the activities of glycolytic enzymes including GP, GAPDH and PK were significantly different among three treatments (Pâ¯<â¯0.05) possibly due to the different modification of protein S-nitrosylation. These results suggest that NO could regulate the glycogen metabolism through modulating the activities of glycolytic enzymes by protein S-nitrosylation.
