13C NMR spectrum of the apolar lipids (AL) fractions extracted from milk cream and dissolved in CDCl3. The spectral regions within the colored rectangles are enlarged, and, in the case of the 130.3–129.5 ppm region, vertically magnified by a factor of 3. The figure reports the assignment of most intense peaks (Sn-1,3 and Sn-2, position of acyl esterification on the glycerol backbone; U and S mean unsaturated and saturated acyl chains, respectively)
