等电点

Isoelectric point

等电点,有时缩写为IEP,是特定分子或表面不带有净电荷的pH。 分子的净电荷受其周围环境的pH影响,并且由于质子的增益或损失而可能变得更加正或负电荷。 表面自然地充电形成双层。 在表面电荷测定离子为H + / OH-的常见情况下,净表面电荷受固体浸没液体的pH的影响。 pI值可以影响分子在给定pH下的溶解度。 这样的分子在对应于其pI的pH和经常从溶液中沉淀出的pH下,在水或盐溶液中具有最小的溶解度。 生物两性分子如蛋白质都含有酸性和碱性官能团。 构成蛋白质的氨基酸本质上可能是阳性,阴性,中性或极性,并且一起产生蛋白质的总体电荷。 在低于其pI的pH下,蛋白质携带净正电荷; 在他们的pI之上,他们承担净负电荷。 The isoelectric point, sometimes abbreviated to IEP, is the pH at which a particular molecule or surface carries no net electrical charge. The net charge on the molecule is affected by pH of its surrounding environment and can become more positively or negatively charged due to the gain or loss, respectively, of protons. Surfaces naturally charge to form a double layer. In the common case when the surface charge-determining ions are H+/OH-, the net surface charge is affected by the pH of the liquid in which the solid is submerged. The pI value can affect the solubility of a molecule at a given pH. Such molecules have minimum solubility in water or salt solutions at the pH that corresponds to their pI and often precipitate out of solution. Biological amphoteric molecules such as proteins contain both acidic and basic functional groups. Amino acids that make up proteins may be positive, negative, neutral, or polar in nature, and together give a protein its overall charge. At a pH below their pI, proteins carry a net positive charge; above their pI they carry a net negative charge.

在英语 词典里isoelectric point的定义

词典中等电点的定义是分子(如蛋白质或氨基酸)的净电荷为零时的pH值。

The definition of isoelectric point in the dictionary is the pH value at which the net electric charge of a molecule, such as a protein or amino acid, is zero.
