L-malic acid in the sample yields NADH (by the following reaction)
It does not contain preservatives that could interfere with the measurements
Method: Two-reagent differential at 405 nm
The configuration of these reagents allows D-glucose/D-fructose (total sugars) to be determined if the enzyme PGI is added or D-glucose to be determined if it is not
In a second reaction
