糖作为三大热源物质之一 ,在体内的代谢情况对机体的机能起着很重要的作用。骨骼肌是机体最主要利用葡萄糖的组织 ,葡萄糖跨膜转运是骨骼肌利用葡萄糖的首要步骤 ,骨骼肌摄取葡萄糖是一种耗能的主动吸收 ,葡萄糖进入肌细胞内需通过细胞膜上的葡萄糖载体的促进扩散 ,ＧＬＵＴ4在 Sugar as one of the three heat source substances in the body’s metabolism plays a very important role in the function of the body. Skeletal muscle is the body’s most important use of glucose tissue, glucose transmembrane transport is the first step in the use of glucose in skeletal muscle, skeletal muscle glucose is an active absorption of energy consumption, glucose into muscle cells through the cell membrane glucose carrier to promote Diffusion, GLUT4 at
