Directions : In the following question, the Assertions (A) and Reason...
The molecular weights of macromolecules ranges to ten thousand Daltons and above. However, lipids, whose molecular weights do not exceed 800 Da, that comes under macromolecular fraction. Lipids are also arranged into structures like cell membrane and other membranes. On grinding, these membrane fragments in the form of vesicles get separated along with the acid insoluble pool and hence in the macromolecular fraction. Hence, lipids are not strictly macromolecules.

Directions : In the following question, the Assertions (A) and Reason...
Assertion: Lipids are not strictly macromolecules.
Reason: Lipids are indeed small molecular weight but because of their association with membranes separate in the macromolecular fraction.
Explanation:
Lipids are a class of biomolecules that include fats, oils, waxes, phospholipids, and steroids. They are characterized by their hydrophobic nature and insolubility in water. Lipids play important roles in energy storage, insulation, cell signaling, and membrane structure.
Macromolecules:
Macromolecules are large molecules composed of smaller subunits called monomers. Examples of macromolecules include proteins, nucleic acids, polysaccharides, and some complex carbohydrates. Macromolecules have high molecular weights and are usually formed by polymerization reactions.
Lipids as macromolecules:
Lipids are not strictly considered macromolecules because they do not form polymers. Unlike proteins, nucleic acids, and polysaccharides, lipids are not composed of repeating monomers. Instead, lipids are composed of smaller subunits such as fatty acids, glycerol, and sterols.
Association with membranes:
While lipids may not be macromolecules themselves, they are often associated with membranes, which are macromolecular structures. The lipid bilayer is a fundamental component of cell membranes and consists of phospholipids and cholesterol. These lipids organize themselves into a double layer, with the hydrophobic tails facing inward and the hydrophilic heads facing outward. This lipid bilayer provides a barrier that separates the cell's interior from its external environment.
Separation in the macromolecular fraction:
Due to their association with membranes, lipids are often separated in the macromolecular fraction during laboratory techniques such as centrifugation or gel filtration chromatography. This separation is based on the size and molecular weight of the molecules. While lipids themselves are not macromolecules, their presence in membranes causes them to be fractionated along with macromolecular structures.
Conclusion:
In conclusion, lipids are not strictly considered macromolecules because they do not form polymers. However, due to their association with membranes, they may be separated in the macromolecular fraction during laboratory techniques. Therefore, both the assertion and reason are true, and the reason is the correct explanation of the assertion. The correct option is A.
