Lactate is an important metabolite in cellular metabolism in health and disease. Its molecular formula is CH3CH(OH)COO-, as seen in the figure below. The scalar coupling between protons A and B in the figure is 7Hz. The chemical shift of one of the proton groups is 4.1ppm and that the other is 1.3ppm. Assuming that the hydroxyl proton (the OH group) does not contribute to the spectrum (fast exchange with H2O protons), draw a schematic spectrum of the lactate ion...
