Structure of Lipids

100.0K
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...

Asymmetric Lipid Bilayer01:35

Asymmetric Lipid Bilayer

10.5K
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%...

Membrane Lipids

35.0K
Lipids are an essential component of all biological membranes. The average lipid content in mammalian membranes is 50%, though it can be as low as 20% in the inner mitochondrial membrane or as high as 80% in the myelin sheath present around the nerve cells.
Phosphatidylcholine, phosphatidylethanolamine, phosphatidylserine, and sphingomyelin are the most common phospholipids present in mammalian membranes. At physiological pH, phosphatidylserine is negatively charged, while the other three...

Assembly 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.
A large chunk of any biological membrane is composed of phospholipids. These lipids have a heterogeneous distribution across different subcellular organelles and even between...

Lipids as Anchors01:32

Lipids as Anchors

7.7K
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.
The carboxy-terminal of most of the prenylated proteins, such as Ras proteins, contains...

Area of Science:

  • Food Science
  • Biotechnology
  • Nutritional Science

Background:

  • Nervonic acid (NA), an ultra-long-chain monounsaturated fatty acid, possesses significant neuroprotective and antioxidant properties.
  • Structured lipids offer a versatile platform for delivering functional fatty acids like NA.
  • Developing efficient methods for NA incorporation into structured lipids is crucial for its application.

Main Methods:

  • Enzymatic interesterification of coconut oil, palm stearin, and NA.
  • Investigating the impact of lipase type, temperature, time, and enzyme dosage on NA content.
  • Employing a machine learning model to predict the sliding melting point of the structured lipid.

Main Results:

  • Optimized conditions (64.6 °C, 7.17 h, 8.46% enzyme) yielded the highest NA content.
  • The resulting NA-rich structured lipid contained 59.34% unsaturated fatty acids, with 46.76% being NA.
  • The structured lipid exhibited β' crystal polymorphism and was suitable as a plastic fat.
