11] A polyketide synthase leads to the formation of the following compound: OH

1. Provide a mechanism for the formation of the compound from its biosynthetic precursors. (I believe it has to do with starting units and extender units and built in a similar way that fatty acids are made?)

2. How many signals would you expect to see in the ¹HNMR and proton decoupled ¹³CNMR of the polyketide (pictured above)?
