B.1.6 Glucose
Glucose measurement is based on the level of H
2
O
2
produced during the enzymatic reaction between glucose
and oxygen molecules in the presence of the glucose oxidase
enzyme. The reaction is described by the following equation:
Glucose Oxidase
Glucose + O
2
––--–––––––––––> Gluconic acid + H
2
O
2
Equation 9
At a constant potential of 0.70 volts, electroactive H
2
O
2
is
oxidized at the surface of the platinum anode as follows:
H
2
O
2
––––––––> 2H
+
+ O
2
+ 2e
-
Equation 10
The current generated by the ow of electrons at the
surface of the platinum sensor is proportional to the glucose
concentration of the sample.
B.1.7 Lactate
Lactate measurement is based on the level of H
2
O
2
produced
during the enzymatic reaction between lactate and oxygen
molecules in the presence of the lactate oxidase enzyme.
The reaction is described by the following equation:
Lactate Oxidase
Lactate + O
2
–––––––––––––> Pyruvate acid +
H
2
O
2
Equation 11
At a constant potential of 0.70 volts, electroactive H
2
O
2
is
oxidized at the surface of the platinum anode as follows:
H
2
O
2
––––––––> 2H
+
+ O
2
+ 2e
-
Equation 12
The current generated by the ow of electrons at the
surface of the platinum sensor is proportional to the lactate
concentration of the sample.
