Which of the above statements are NOT correct? S1: The acid-soluble pool consists of small biomolecules with molecular weights typically ranging from 18 to around 800 Daltons. S2: Proteins, nucleic acids, and polysaccharides are the only organic compounds found in the acid-insoluble fraction. S3: Lipids are classified as true biomacromolecules because their molecular weight inherently exceeds 1000 Daltons. S4: The acid-insoluble fraction represents roughly the cytoplasmic composition, including both micromolecules and macromolecules. S5: The disruption of cell membranes during grinding leads to the formation of water-insoluble vesicles, causing lipids to separate into the acid-insoluble pool.
