Regarding groups and ratios between the different classes of fatty acid, it can be found in Figure 3.2 that the saturated fatty acid (SFA) had the combined value of 57.01% and the unsaturated fatty acid (USFA) had an aggregated value of 42.99% of which the monounsaturated fatty acid (MUSFA) subclass was dominant.
The ratio of saturated to unsaturated fatty acids (SFA:USFA) was calculated as 1.33. Ratio of this sort represented the relation between two major fatty acid groups and value 1.33 indicated that a high proportion of fatty acid profile of the PFAD sample was composed of SFA when compared with USFA as seen in Fig 3.2.
