Cell Membrane Disruption & Lipid Separation — NEET Biology
📚 Practice ConceptWhen we grind a tissue, we are disrupting the cell structure. Cell membrane and other membranes are broken into pieces, and form vesicles which are not water soluble. Therefore, these membrane fragments in the form of vesicles get separated along with the acid insoluble pool and hence in the macromolecular fraction. Lipids are not strictly macromolecules.
Match the following biomolecules or fractions with their predominant characteristics or components: COLUMN I (Biomolecule/Fraction) A. Amino acids B. Lipids C. Nucleic Acids D. Polysaccharides E. Ash COLUMN II (Characteristic/Component) i. Hydrolysed to monosaccharides ii. Polymers of nucleotides iii. Contain an amino and an acidic group iv. Water insoluble and form vesicles in acid-insoluble fraction v. Contains inorganic residues after combustion
