Question

Draw the structure of L-valine in a strongly basic solution?

What is the charge of this amino acid in a strongly basic solution?

What is the pH of D at its isoelectric point?

Answer 1

The isoelectric point (pI, pH(I), IEP), is the pH at which a molecule carries no net electrical charge or is electrically neutral in the statistical mean. The standard nomenclature to represent the isoelectric point is pH(I).
