Content of Trans Fatty Acids in Human Cheek Epithelium: Comparison with Serum and Adipose Tissue

Figure 1

Chromatogram showing the fatty acid profile in a representative Cheek Epithelium sample. The numbers above the peaks are the retention time. The first peak is the solvent peak. The arrow shows the C:17 peak which was added as internal standard. The trans fatty acid peaks occur at the following retention times in this sample: 16:1t (36.53), 18:1t (43.33), 18:2 (45.46, 46.23, 46.43), and 18:3t (48.54, 50.33, 52.34, 53.30, 54.04, 54.59), respectively.
