Abstract

The qualitative and quantitative lipid composition of nuclei and nuclear membranes from pig and rat liver were determined. These determinations were compared with the corresponding data obtained for microsomes from the same material after similar treatments. The results indicate that, at least, by far the major part of the nuclear lipids is located in the membranes of the nuclear envelope. The phospholipid pattern of the nuclear membranes and the endoplasmic reticulum (ER) membranes in general is widely identical in both species. As a striking difference in the lipid composition, however, a fourfold increase of esterified cholesterol in the nuclear membranes was found. In a quantitative approach the ratio of total surface area of the nuclear lipids to the total surface area of the nuclear envelope membranes was calculated as being 3.6, a value which fairly approximates the requirements of a bimolecular lipid leaflet model.

摘要

测定了猪和大鼠肝脏细胞核及核膜的定性和定量脂质组成。将这些测定结果与对相同材料经类似处理后得到的微粒体的相应数据进行了比较。结果表明,至少到目前为止,细胞核脂质的主要部分位于核膜。两种物种的核膜和内质网(ER)膜的磷脂模式总体上广泛相同。然而,作为脂质组成的一个显著差异,发现核膜中酯化胆固醇增加了四倍。在定量分析中,计算出核脂质的总表面积与核膜总表面积的比值为3.6,该值相当接近双分子脂质小叶模型的要求。
