摘要
猪的肌纤维根据肌球蛋白重链(MyHC)的多态性可分为1,2 a.2b和2x 4种类型,在代谢上分别与慢速氧化型、快速氧化型、快速酵解型和中间类型相对应。肌纤维的生成在分子水平上受到肌细胞生成素基因的精确调控,肌纤维的类型在生长过程中不断发生转化,并受营养和非营养等因素的影响。肌纤维的类型对肉的品质有着重要的影响。
The classification of muscle fiber types according to myosin heavy chain (MyHC) polymorphism is 1,2a, 2b and 2x, which correspond to the slow-oxidative type, fast oxidative-glycolytic type, fast glycolytic type and the mediate type by the metabolism. The generation of muscle fiber is regulated exactly by the myogenin gene on the molecular lever. The muscle fiber type convert in the process of growth constantly, and it is influenced by nutrition and others factors. The type of muscle fiber affects the pork quality remarkably .
