Figure 1. TEM images (A–C) and biochemical determination of triacylglycerol (TAG) content (D) and TAG esterification rates (E) in heart muscle from lean and obese Zucker rats.

Data are expressed as the mean ± s.e.m. Images were taken at 10,500× magnification, and the black scale bar is 2 μm. n = 5–6 animals for each experiment. White arrows indicate lipid droplets. *Significantly different (P < 0.05) from lean animals.
