What might be concluded upon determining that an unknown amino acid has its isoelectric point near pH 10?

Question

Quizplus · Accepted Answer

The isoelectric point is the pH at which the amino acid has no net charge. Therefore, if the isoelectric point is near pH 10 (which is basic), it means that the amino acid is more likely to have basic groups in its side chain than acidic groups. Basic groups such as amino (NH₂) and imino (NH) groups can accept protons (H⁺) at lower pH values, which makes the amino acid positively charged. At high pH values, however, these groups are protonated and neutral, which makes the amino acid negatively charged. Therefore, an amino acid with more basic groups than acidic ones would have its isoelectric point close to pH 10.
