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.

摘要

测定了两只产蛋火鸡血浆“低密度组分”（LDF，d小于1.006）脂蛋白的周转率。通过注射1-14C-棕榈酸来标记LDF，该棕榈酸被整合到循环LDF的甘油三酯（TG）中。根据超速离心分离的LDF的浓度和半衰期（t1/2）来确定周转率。这些值分别为每毫升血浆22微当量的TG脂肪酸（TGFA）和431分钟。LDF的周转率为每天17.57毫当量TGFA或每天5.0克作为硬脂酸的TGFA。据估计，每天有3.2克LDF-TGFA作为蛋黄被去除。
