| 摘 要： | 乳酸生成后的代谢去向主要是氧化清除.乳酸可以生成部位通过组织间隙和血液穿梭到邻近的高氧化能力部位.乳酸跨膜运输是在一元羧化乳酸运输蛋白(MCT)协助下沿浓度梯度和PH进行的.通过训练,骨胳肌和心肌细胞的MCT1含量会增加,结果摄取乳酸增加,乳酸生成后从骨胳肌外流增加.更重要的是,线粒体膜也含有MCT,这有助于乳酸在此进行氧化.

| Abstract: | Most of the lactate produced is removed by oxidation.Lactate can shuttle through the interstitium and blood from areas of production to areas of high oxidated ability.Muscular lactate is transported across membranes along concentration gradient and PH by monocarboxylate transporter(MCT).With training,MCT1 is increased in muscular tissues,resulting in an increased uptake of lactate and an increased lactate efflux out of muscle.More importantly,there are mitochondrial MCTs,which help lactate flux for oxidation. |
