Coenzyme Q cytochrome C reductase (Complex III) [Enzymatic activity/mass] in Tissue   74586-9

LOINC Code


LOINC code74586-9
nameCoenzyme Q cytochrome C reductase (Complex III) [Enzymatic activity/mass] in Tissue
descriptionDetermination of complex III activity by spectroscopy at 550 nm quantification. Complex III transfers electrons from ubiquinol or CoQ10 towards cytochrome c. The activity is inhibited by antimicina. It measures the increase in absorbance at 550 nm wavelength of the reduced cytochrome c. The final activity was calculated using the difference between the activity measured with and without antimicina.
statusACTIVE

Fully-Specified Name

componentCoenzyme Q cytochrome C reductase
propertyCCnt  =  Catalytic Content
timePt  =  Point in time:  To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements.
systemTiss  =  Tissue, unspecified
scaleQn  =  Quantitative:  The result of the test is a numeric value that relates to a continuous numeric scale. Reported either as an integer, a ratio, a real number, or a range. The test result value may optionally contain a relational operator from the set {<=, <, >, >=}. Valid values for a quantitative test are of the form "7", "-7", "7.4", "-7.4", "7.8912", "0.125", "<10", "<10.15", ">12000", 1-10, 1:256
