酶活测定中的一种试剂
DL-mevalonate
上述物质是在测定酶活时加入的,我知道是加强戊酸,但他前面的那个DL不知道什么意思,还望高手指教!
原文如下:
Routine measurement of enzyme activity was performed spectrophotometrically at 30°C by using a 1.0-ml mixture which contained 100 umol of HEPES (pH 7.5), 100 umol of KCl, 0.2 umol of phosphoenolpyruvate, 0.5 umol of DTT, 0.16 umol of NADH, 10 umol of MgCl2, 4 U of lactate dehydrogenase, 4 U of pyruvate kinase, 5.0 umol of ATP, and 0.8 umol of DL-mevalonate.
