Verified step by step guidance

Understand the concept of hydrophilic domains: Hydrophilic domains are regions of a molecule that interact favorably with water due to their polar or charged nature. Molecules lacking hydrophilic domains are typically nonpolar and do not interact well with water.

Analyze the molecular structure of monosaccharides: Monosaccharides are carbohydrates with multiple hydroxyl (-OH) groups, which are polar and hydrophilic. Therefore, monosaccharides have hydrophilic domains.

Examine globular proteins: Globular proteins are composed of amino acids, many of which have polar or charged side chains. These proteins often have hydrophilic domains on their surface to interact with the aqueous environment.

Evaluate pure hydrocarbon chains (e.g., saturated fatty acids): Pure hydrocarbon chains consist of nonpolar covalent bonds between carbon and hydrogen atoms. These chains lack polar or charged groups, making them hydrophobic and devoid of hydrophilic domains.

Consider amphipathic phospholipids: Amphipathic phospholipids have both hydrophilic and hydrophobic regions. The hydrophilic domain is typically the phosphate group, while the hydrophobic domain consists of the hydrocarbon tails. Thus, they do not lack hydrophilic domains.
