Isoelectric point is pH at which?

Options

  1. AAn amino acid becomes acidic.
  2. BAn amino acid becomes basic.
  3. CZwitter ion has net positive charge.
  4. DZwitter ion has net zero charge.

Correct answer

D. Zwitter ion has net zero charge.

Step-by-step solution

The isoelectric point is the neutral state of the molecule or it is the pH of a solution that caries net zero charge or total positive charge must be equal to the total negative charge. Zwitter ion has a net zero charges.
