Relative concentrations of fatty acids from least squares fit of experimental Raman measurements of lipid droplets for individual FAMEs-treated LNCaP without SVM (a) and with SVM (b). Standard deviations are shown. OA oleic acid, POA palmitoleic acid, LOA linoleic acid, AA arachidonic acid, PA palmitic acid, SA stearic acid. All FAMEs sample were liquids, except the PA and SA samples. PA and SA samples spectra were recorded in liquid form and solid form as well by melting the solid samples with a heat gun. The final spectra for PA and SA samples were an average spectra between the liquid and solid form spectra
