Question

what are lipids? complex carbohydrates like starch; polymers made of amino acids; fatty acids not generally soluble in water; monomers that store and transfer genetic information

Explanation:

To determine the correct description of lipids, we analyze each option:

• "Complex carbohydrates like starch" describes carbohydrates, not lipids.
• "Polymers made of amino acids" describes proteins, as proteins are polymers of amino acids.
• "Fatty acids not generally soluble in water" matches the definition of lipids, as lipids are hydrophobic (not soluble in water) and often involve fatty acids.
• "Monomers that store and transfer genetic information" describes nucleotides (for nucleic acids), not lipids.

Answer:

Fatty acids not generally soluble in water
