Vedclass · Answer

(B) Lipids are not strictly macromolecules in the same sense as proteins or nucleic acids because they are not polymers of repeating monomeric units. However,they are classified as biomolecules that are found in the acid-insoluble fraction during chemical analysis of tissues. Despite their presence in the acid-insoluble fraction,their molecular weight is generally $800$ Daltons or less. Therefore,lipids are considered to be small molecular weight compounds compared to true macromolecules like proteins and polysaccharides.
