Abstract

The dry mass, wet mass, and volume of mitochondria of normal rat liver were determined, as well as nitrogen content and concentration. A scheme of multiple approaches to these quantities was devised, permitting comparison of values obtained by independent methods. The following basic values are considered highly accurate: Mean dry mass, 13.6 x 10(-14) g; mean wet mass, 51.8 x 10(-14) g; mean volume, 0.43 micro(3); nitrogen content, 1.75 x 10(-14) g The work emphasizes the fact that in mitochondria the quantities, mass, and volume occur in logarithmic-normal distributions.

摘要

测定了正常大鼠肝脏线粒体的干质量、湿质量和体积,以及氮含量和浓度。设计了一种对这些量进行多种测量方法的方案,以便比较通过独立方法获得的值。以下基本值被认为是高度准确的:平均干质量,13.6×10⁻¹⁴克;平均湿质量,51.8×10⁻¹⁴克;平均体积,0.43立方微米;氮含量,1.75×10⁻¹⁴克。这项研究强调了这样一个事实,即线粒体中的质量、体积等参数呈现对数正态分布。
