摘要
根据肌球蛋白重链的多态性可将猪的肌纤维分为Ⅰ,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。从肌纤维的构成、分类及转化等方面介绍肌纤维类型的代谢特点,重点阐述肌纤维类型对猪肉品质的影响,以及影响肌纤维类型的因素。
Myofiber types are classified into four types, which are I , 2a, 2b and 2x, according to myosin heavy chain polymorphism. The' four fiber types represent four metabolic features that are slow oxidative type, fast oxidative type, fast glycolytic type and mediate type. In this article, myofiber types from myofiber constitution, classification, characteristics and transformation were introduced. Meanwhile, it is principal to expound how myofiber types affect the pork quality, and the factors influencing myofiber types.
