Why are lipids not macromolecules?

Answer 1

No, lipids are actually macromolecules. Lipids or fats are made up of fatty acids and glycerol. They are functioning as insulators, forms cell membrane, hormones, and can provide energy.

Answer 2

Lipids are not considered macromolecules because they are typically smaller in size compared to true macromolecules like proteins, nucleic acids, and polysaccharides. While lipids play important roles in biological systems, they are generally composed of simpler structures such as fatty acids, glycerol, or sterols.
