Summary
Fullerene C(60) demonstrates antioxidant properties by preventing lipid autoxidation. It protects unsaturated lipids and solvents from oxidation, converting into an epoxide C(60)O.
Area of Science:
- Materials Science
- Chemistry
- Biochemistry
Background:
- Unsaturated lipids are prone to autoxidation when exposed to air.
- Fullerene C(60) is a carbon allotrope with unique electronic properties.
Purpose of the Study:
- To investigate the antioxidant activity of fullerene C(60) in unsaturated lipids and solvents.
- To elucidate the mechanism and kinetics of C(60) oxidation in lipids.
Main Methods:
- Spectrophotometric analysis of lipids and solvents with dissolved C(60).
- Comparison of C(60) with a known antioxidant (TMPPD).
- Kinetic studies under dark and UV irradiation conditions.
Main Results:
- Fullerene C(60) effectively inhibits autoxidation of unsaturated lipids and solvents.
- C(60) is oxidized to an epoxide (C(60)O) during the process.
- The antioxidant mechanism of C(60) in lipids was proposed and studied.
Conclusions:
- Fullerene C(60) exhibits significant antioxidant activity, protecting against lipid autoxidation.
- The study provides insights into the mechanism and kinetics of C(60) as an antioxidant.

01:35Asymmetric Lipid Bilayer
Biological membranes show uneven distribution of different types of lipids in the inner and outer layers, resulting in transverse asymmetric membranes. The treatment of the erythrocyte membrane with the enzyme phospholipase confirmed the asymmetric nature of the lipid bilayer. The enzyme hydrolyzes lipids into fatty acids and hydrophilic groups. The phospholipase acts only on the outer layer of the membrane, while the inner layer remains intact. The phospholipase treatment resulted in 80%...
01:32Lipids as Anchors
In the plasma membrane, the lipids forming the bilayer can also act as an anchor to tether proteins to the membrane. The three main types of lipid anchors found in eukaryotes are – prenyl groups, fatty acyl groups, and glycosylphosphatidylinositol or GPI groups. Prenyl and fatty acyl groups act as anchors on the cytosolic surface of the membrane, whereas GPI anchors proteins on the extracellular side.

03:38Structure of Lipids
Lipids include a diverse group of compounds that are largely nonpolar in nature. This is because they are hydrocarbons that include mostly nonpolar carbon-carbon or carbon-hydrogen bonds. Non-polar molecules are hydrophobic (“water fearing”), or insoluble in water. Lipids perform many different functions in a cell. Cells store energy for long-term use in the form of fats. Lipids also provide insulation from the environment for plants and animals. For example, they help keep aquatic birds and...

01:28Assembly of the Lipid Bilayer in the ER
Biological membranes are more than just a barrier separating cell cytoplasm from the outside environment. They are highly dynamic and help maintain the integrity and physiological stability of the cells as well as membrane-bound organelles. Membranes also play vital roles in cell-to-cell and intracellular communication.
