Question

what is the monomer unit of lipids? nucleotide fatty acid amino acid monosaccharide

Explanation:

To determine the monomer of lipids, we analyze each option:

• Nucleotides are monomers of nucleic acids (e.g., DNA/RNA), so this is incorrect.
• Fatty acids (along with glycerol) are the monomer - like units of lipids. Lipids are typically formed from the combination of fatty acids and glycerol, and fatty acids are a key building - block - like component for many lipid structures.
• Amino acids are the monomers of proteins, so this is incorrect.
• Monosaccharides are the monomers of carbohydrates (e.g., glucose is a monosaccharide and is the monomer for starch, glycogen, etc.), so this is incorrect.

Answer:

Fatty acid
