Summary
Nuclear magnetic resonance (NMR) spectroscopy characterizes lyotropic lipidic cubic phases (LCPs). Solution NMR reveals LCP structure, dynamics, and hydration for applications in drug delivery and protein crystallization.
Area of Science:
- Biophysical Chemistry
- Materials Science
- Structural Biology
Background:
- Lyotropic lipidic cubic phases (LCPs) are self-assembled lipidic materials with complex geometries.
- LCPs are utilized in membrane protein crystallization and as matrices for drug delivery.
- Understanding LCP structural and dynamic properties is crucial for their applications.
Purpose of the Study:
- To systematically review the characterization of LCPs using solution Nuclear Magnetic Resonance (NMR) spectroscopy.
- To highlight the versatility of solution NMR for probing LCP properties.
- To provide insights into the application of LCPs in various fields.
Main Methods:
- Solution NMR spectroscopy was employed to analyze LCPs formed by monoolein (MO).
- Techniques included spectral perturbation analysis, hydration level quantification, and 13C relaxation measurements.
- Pulsed-gradient spin-echo (PGSE) NMR was used to measure translational diffusion.
Main Results:
- Solution NMR effectively characterizes LCPs, including spectral changes with additives and hydration quantification.
- Atom-specific dynamics along the MO hydrocarbon chain were elucidated using 13C relaxation.
- Translational diffusion measurements correlated with drug release profiles, and protein encapsulation was demonstrated.
Conclusions:
- Solution NMR is a powerful tool for comprehensive characterization of LCPs.
- NMR provides detailed insights into LCP structure, dynamics, and interactions.
- This review underscores the potential of NMR for advancing LCP applications in drug delivery and structural biology.

01:19Fluid Mosaic Model
12.1K
Scientists identified the plasma membrane in the 1890s and its principal chemical components (lipids and proteins) by 1915. The model for plasma membrane structure, proposed in 1935 by Hugh Davson and James Danielli, was the first model to be widely accepted in the scientific community. The model was based on the plasma membrane's "railroad track" appearance in early electron micrographs. Davson and Danielli theorized that the plasma membrane's structure resembled a sandwich...

Membrane fluidity is explained by the fluid mosaic model of the cell membrane, which describes the plasma membrane structure as a mosaic of components—including phospholipids, cholesterol, proteins, and carbohydrates—that gives the membrane a fluid character.
Mosaic nature of the membrane
The mosaic characteristic of the membrane helps the plasma membrane remain fluid. The integral proteins and lipids exist as separate but loosely-attached molecules in the membrane. The membrane is...

88.9K
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...

01:34The Fluid Mosaic Model
149.3K
The fluid mosaic model was first proposed as a visual representation of research observations. The model comprises the composition and dynamics of membranes and serves as a foundation for future membrane-related studies. The model depicts the structure of the plasma membrane with a variety of components, which include phospholipids, proteins, and carbohydrates. These integral molecules are loosely bound, defining the cell’s border and providing fluidity for optimal function.

At room temperature, the chair conformer of cyclohexane undergoes rapid ring flipping between two equivalent chair conformers at a rate of approximately 105 times per second. These two chair conformers are in equilibrium. The rapid ring flipping results in the interconversion of the axial proton to an equatorial proton and an equatorial to the axial proton. Such interconversions are too rapid and cannot be detected on the NMR timescale. Hence, the NMR spectrometer cannot distinguish between the...
