Globular proteins are generally soluble in water due to their hydrophilic (water-loving) amino acid side chains, which form hydrogen bonds with water molecules. Fibrous proteins, on the other hand, are generally insoluble in water due to their hydrophobic (water-fearing) amino acid side chains, which prefer to interact with other hydrophobic molecules rather than water.
