具有不同颜色稳定性的牛肌肉（背最长肌、阔筋膜张肌、腰大肌、内侧膈肌）用于测量不同条件下的“高铁肌红蛋白还原酶活性”。分析了 pH 值和温度对体外高铁肌红蛋白还原的影响。通过差速离心，最高的高铁肌红蛋白还原酶活性位于微粒体和或多或少完整的线粒体中。从颜色的角度来看，最不稳定的肌肉呈现出最高的减少活动，并且在有氧或无氧条件下测量的活动之间没有发现差异。
Cow muscles (Longissimus dorsi, Tensor fasciae latae, Psoas major, Diaphragma medialis), with different colour stabilities, were used to measure ''Metmyoglobin reductase activity'' in different conditions. The effects of pH and temperature on in vitro metmyoglobin reduction were analysed. The highest metmyoglobin redutase activity was localized in microsomes and in more or less intact mitochondria by means of differential centrifugations. The most unstable muscles, from the colour point of view, presented the highest reducing activities and no differences were noted between activities measured in aerobic or anaerobic conditions.
