是否由于能量摄入和消耗上仅很小不平衡或由于不像其它人那样好利用脂肪酸,以致有些人比其它人肥胖?此假说提示个体间每日生活中,在供能的分解代谢性生化途径上持续存在着差异。慢肌纤维(Ⅰ型)富含线粒体,氧化并利用脂肪酸作为乙酰辅酶 A 的重要来源。快肌纤维(Ⅱ型)含较少线粒体,通常是通过糖酵解途径提供能量。不同个体的肌纤维类型比例差别很大。股外侧肌最常用作活检研究,此肌含慢肌 Are some people obese more obese than others due to a small imbalance in energy intake and consumption, or the lack of use of fatty acids as well as others? This hypothesis suggests that in everyday life between individuals, catabolic biochemical There are persisting differences in the way. Slow muscle fibers (type I) are rich in mitochondria, oxidize and utilize fatty acids as an important source of acetyl-CoA. Fast muscle fibers (type II) contain less mitochondria, usually through the glycolysis pathway to provide energy. Different individuals have very different proportions of muscle fibers. The lateral femoral muscle is most commonly used as a biopsy, and this muscle contains slow muscles
