isoelectric
Adjective
Meaning
isoelectric (not comparable)
Having equal electric potential, or the same number of positive and negative charges.
Phrases with the word
Examples
Glycine may exist as a zwitterion at the isoelectric point, but the equilibrium constant for the isomerization reaction in solution :H 2 NCH 2 CO 2 H ⇌ H 3 N + CH 2 CO 2 − is not known.
Examples In these two examples the isoelectric point is shown by the green vertical line.
In addition, precise measurement of isoelectric points is difficult and requires careful techniques, even with modern methods.
In the case that there is one species of each type, the isoelectric point can be obtained directly from the pK values.
The individual amino acids all have slightly different pKa values, so have different isoelectric points.
Thus, many sources often cite differing values for isoelectric points of these materials.
