(a) Selected region of a 500 MHz 1H-NMR spectrum of the lipid fraction of a lyophilized bovine milk sample in CDCl3. (b) Magnification of the respective 1H-NMR regions T= 298 K; number of scans, 256; acquisition time 4.3 s; relaxation delay, 5 s; total experimental time ~25 min). (c) and (e) 1D TOCSY spectra; (d) and (f) are the magnification of the respective 1H-NMR regions, τm = 200 ms, number of scans, 256 and total experimental time ~25 min; the asterisks (*) denote the resonances of the allylic protons that were excited with the use of a selective shaped pulse of 80 ms.
