Verified step by step guidance

Understand the hydrophobic effect: The hydrophobic effect refers to the tendency of nonpolar molecules to aggregate in aqueous environments, minimizing their interaction with water. This is due to the inability of nonpolar molecules to form hydrogen bonds with water.

Analyze the solubility of nonpolar molecules: Nonpolar molecules, such as triglycerides, lack polar groups and are hydrophobic. They are most likely to dissolve in fat because fat is a nonpolar solvent, and 'like dissolves like' is a key principle in solubility.

Evaluate polar molecules: Polar molecules, such as glucose, have polar functional groups (e.g., hydroxyl groups) that can form hydrogen bonds with water. These molecules are more soluble in water than in fat due to their polarity.

Consider ionic compounds: Ionic compounds, such as sodium chloride, dissociate into charged ions in water and interact strongly with water molecules through ion-dipole interactions. These compounds are highly soluble in water but not in fat.

Assess small peptides with charged side chains: Small peptides with charged side chains contain polar or ionic groups, making them hydrophilic. These peptides are more likely to dissolve in water rather than fat due to their charged nature.
