Aspartic acid and glutamatic acid can form hydrogen bonds with water because they _____.

Question

have phosphate groups in their side chains.

have nonpolar, hydrophobic side chains.

have polar, uncharged sided chains.

have electrically charged side chains.

have sulfhydryl groups in their side chains.

Answer 1

Poorly worded question. Neither amino acid has a “side chain”. They both form hydrogen bonds with water because they both have amino groups and carboxly groups (not considered side chains, by the way). Both are capable of hydrogen bond formation.
