title: The turnover rate of lipoprotein of d less than 1.006 from plasma of laying turkey hens.
abstract: The turnover rate of plasma "lower density fraction" (LDF, d less than 1.006) lipoprotein was determined in two laying turkey hens. LDF was labeled by injecting 1-14C-palmitate which was incorporated into the triglyceride (TG) of circulating LDF. The turnover rates were determined from concentration and half life (t1/2) of the ultracentrifugally-isolated LDF. These values were 22 mu equiv. of TG fatty acid (TGFA) per ml. plasma and 431 min. The turnover rate of LDF was 17.57 mili equiv. TGFA/day or 5.0 g. of TGFA/day as sterate. It was estimated that 3.2 g. of LDF-TGFA/day were removed as egg yolk.
