FIG. 2.

Spectra of H1_α-D-glucose signals from both in vitro NMR samples of one rat. The spectra were obtained from the “minus” (a) and “plus” samples (b) at 14.1-T. The vertical scale was normalized based on the intensity of the creatine CH2 peak signal at 3.93 ppm (not shown). ¹³C-H1_α in the figure represents the H1_α protons bound to ¹³C, and ¹²C-H1_α reflects those protons bound to ¹²C.
