Plasma pool (nmol) of 3,4-didehydroretinol (DR) + R, R, and DR calculated by multiplying the serum concentration of each compound as measured by HPLC with an estimate of plasma volume (0.038 ml/g BW) (37). A: 21% fat group; B: 6% fat group. DR + R (solid line with square), R (long-dashed line with diamond), and DR (dashed line with triangle). Repeated measures using Tukey adjustment for multiple comparisons significantly different from t = 0 for each compound indicated by *; adjusted P value < 0.05. n = 4 per time; except n = 7 at 5 h for 6% fat fed rats, n = 3 and 9, respectively, at 2 and 5 h for 21% fat fed rats. Values are means ± SD.
