Detailed explanation-1: -Lipids aren’t polymers since they lack a monomer unit. Simply put, lipids are a type of fat having a glycerol molecule and a two or three fatty acid chain. Although there is always one glycerol, the number of fatty acids varies.
Detailed explanation-2: -Correct answer: Lipids are not “true” polymers because lipids are not composed of repeating units of the same molecules or atoms. Explanation: Polymers are molecules that are made of two or more repeating units of the same molecule or atom.
Detailed explanation-3: -Lipids are unique compared to the other three biological macromolecules because there are two different monomers for lipids. There is only one monomer for carbohydrates (monosaccharides), proteins (amino acids), and nucleic acids (nucleotides). Lipids’ monomers are glycerol and fatty acids.
