Question

which of the following is a characteristic of lipids? made up of amino acids contains nitrogen soluble in water insoluble in water

Explanation:

• "Made up of amino acids" is a characteristic of proteins, not lipids.
• Lipids typically do not contain nitrogen (unlike proteins or nucleic acids).
• Lipids are non - polar molecules, and water is a polar molecule. According to the principle of "like dissolves like", lipids are insoluble in water.
• So the correct characteristic of lipids is being insoluble in water.

Answer:

D. Insoluble in water (assuming the options are labeled A: Made up of amino acids, B: Contains nitrogen, C: Soluble in water, D: Insoluble in water)
