    Alkyl Esters Other than Methyl - lipidlibrary.aocs

    The methyl group in the propyl ester is more remote from the oxygen, shifting it upfield close to the signal of the terminal methyl of the fatty acid chain. The theoretical integration value of the large methylene signal is therefore reduced to 28. Figure 2. 1 H-NMR spectrum of propyl stearate. Butyl esters.
