Because of the amido and carboxyl, amino acid is ampholyte so that it exists as a sort of zwitterions or dipole ionic when it dissolves in the water or in crystal.

氨基酸同时含有氨基和羧基，是两性电解质，在水溶液或结晶内基本上均以两性离子或偶极离子的形式存在。

This technology can form smooth pH gradient by adding ampholyte and make protein stop electrophoresis at the isoelectric points.

该技术是通过加入两性电解质，形成较平滑pH梯度，使样品在等电点处停止电泳。

The new equipment can be applied to separate inorganic ions and some improvements for equipment and further research on conditions of electrophoresis should be undertaken to separate ampholyte amino acid.

新设计的垂直电泳装置适合用于无机离子的分离，如用于分离两性电解质氨基酸还需进一步研究电泳条件或改进装置。

应用国产两性电解质对动物血红蛋白谱型的分析

It can also be applied to determine ampholyte such as protein and amino acid.

该计算公式也可应用到蛋白质、氨基酸等两性电解质的线性滴定分析上。
