Isoelectric point is pH at which?
Options
- AAn amino acid becomes acidic.
- BAn amino acid becomes basic.
- CZwitter ion has net positive charge.
- 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.
