应用

乳酸用作有机合成(生产粘合剂)中的试剂。它用于皮革、纺织和制革工业。它可用作增塑剂、催化剂或酸化剂。乳酸甚至被用作烟草制品生产中的调味剂。

生化/生理作用

在动物体内,乳酸是一种由增殖细胞和在剧烈运动等无氧条件下产生的代谢化合物。乳酸可被氧化回丙酮酸或通过糖异生转化为葡萄糖。乳酸在几种哺乳动物物种和早期脑发育过程中优先被神经元代谢。

Using a prospective, randomized study design we demonstrate that midazolam sedation minimizes acidosis compared with physical restraint in captive juvenile estuarine crocodiles during handling or noninvasive procedures at preferred body temperature. A dose of midazolam (5.0 mg/kg) was administered intramuscularly
