Blood glutathione peroxidase activity and selenium levels were found to correlate well, indicating that glutathione peroxidase activity can be used to assess blood selenium levels in beef cattle. The glutathione peroxidase activity of blood is less stable than is the selenium concentration but when blood was stored at 4 degrees C, the glutathione peroxidase activity remained constant for seven days.
研究发现，血液中的谷胱甘肽过氧化物酶活性与硒水平密切相关，这表明谷胱甘肽过氧化物酶活性可用于评估肉牛的血液硒水平。血液中谷胱甘肽过氧化物酶的活性不如硒浓度稳定，但当血液保存在4摄氏度时，谷胱甘肽过氧化物酶活性在七天内保持不变。
