The enzymatic systems responsible for the de novo biosynthesis of saturated fatty acids

and polyketide natural products share many similarities including the utilization of

common precursors, similar chemistry, similar structures and overall architectural design.

Compare and contrast saturated fatty acid biosynthesis with polyketide biosynthesis to

explain how two systems are adapted for completely different functions. The former is

involved in primary metabolism and dedicated for synthesis of fatty acids whereas latter is

endowed with the task of creating a diverse range of complex natural products as shown

above.
