The following figure represents a globular protein - VCE - SSCE Biology - Question 1 - 2011 - Paper 1

The molecule is likely to be highly soluble in water due to the presence of hydrophilic (water-attracting) R groups on its surface. These hydrophilic groups can form hydrogen bonds and interact favorably with water molecules, facilitating solvation. In contrast, the presence of hydrophobic R groups positioned in the interior of the protein structure helps to stabilize the protein's conformation while minimizing interactions with water. This arrangement enhances overall solubility in an aqueous environment.
