AIM:The aim of this study was to compare the plasma exposure and tissue accretion of docosahexaenoic acid (DHA) in response to oral dosing of free carboxylic acid (OM3CA) and ethyl ester (OM3EE) forms. MATERIALS AND METHODS:Sixteen adult male Wistar rats, fed a low-fat, carbohydrate-rich, standard chow diet, were chronically catheterized and gavaged for 5 consecutive days with either OM3CA (n = 9) or OM3EE (n = 7), the last day fasted overnight and spiked respectively with either 14C-DHA or 14C-DHA-ethyl ester (14C-DHA-EE) tracers. Appearance of 14C-labelled plasma polar and neutral lipids over 4 h and retention of 14C-activity (R) in the tissues at 4 h were measured. RESULTS:Compared to OM3EE, OM3CA resulted in 2- and 3-fold higher areas under the plasma 14C-labelled polar and neutral lipid curves (exposures), respectively, as well as, higher R in all tissues examined. For both OM3CA and OM3EE, R varied in a tissue specific manner; highest in liver, followed by red skeletal muscle, adipose tissue, brain and white skeletal muscle. Multiple linear regression analysis revealed that R in each tissue (except liver) was dependent on polar lipid exposure alone (r2>0.87 and P |
