Lipid metabolism in muscle cells from lean and obese subjects. A, FA uptake; B, CD36 protein; C, complete oxidation of FA; D, acid-soluble metabolites; E, the ratio of incomplete oxidation of FA (acid-soluble metabolites) to the complete oxidation of FA; F, glycerolipid synthesis; and G, FA esterification into lipid intermediates in the muscle cells of lean and severely obese subjects (n = 8) incubated with 250 μm [1-14C]oleate. Data are represented as mean ± se. *, Significantly different from lean controls (P < 0.05).
