Verified step by step guidance

Understand the definition of lipids: Lipids are a diverse group of organic compounds that are insoluble in water but soluble in organic solvents. They include fats, oils, waxes, phospholipids, and steroids.

Identify the common characteristic of lipids: The key feature that all lipids share is their hydrophobic nature, meaning they do not dissolve in water. This is due to their long hydrocarbon chains or rings.

Evaluate the options given: Analyze each option to determine if it aligns with the known characteristics of lipids.

Option analysis: Lipids do not contain nitrogen as a common element, they are not composed of amino acids, and they are not polymers of glucose. These characteristics are more aligned with proteins and carbohydrates.

Conclude with the correct characteristic: Based on the analysis, the correct characteristic that all lipids share is their insolubility in water, which is due to their hydrophobic nature.
