Question

Acidic side chains (such as Aspartic acid and Glutamic acid) contain negatively charged functional groups and are hydrophilic. Basic side chains (such as Arginine, Lysine, and Histidine) contain positively charged functional groups and are also hydrophilic. Polar but neutral side chains (such as Serine, Threonine, and Tyrosine) have partial charges and can form hydrogen bonds with water molecules, making them hydrophilic as well. Therefore, all three types of side chains are hydrophilic.
