Nelson's test was first performed in standard glucose solutions to generate a linear equation to determine the concentration of D-glucose hydrolyzed from the glycogen isolate. The linear equation is constructed by plotting the concentration of standard glucose (in mM) on the x-axis against the absorbance of the resulting mixture at 510 nm on the y-axis. As such, the general form of the linear equation is: Abs = slope (in mM-1) [glucose] (in mM) + y - intercept
