In general, when you state analyzing a 13 C NMR, split the spectrum in two parts by drawing a line at 100 ppm; below this value you have the saturated functional groups, and beyond that is the unstructured region. Each peak corresponds to a distinct chemical environment while the area under the peak is proportional to the number of nuclei in a given environment.
