Fluid Mosaic Model01:19

Fluid Mosaic Model

11.4K
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 Fluidity01:23

Membrane Fluidity

151.1K
Cell membranes are composed of phospholipids, proteins, and carbohydrates loosely attached to one another through chemical interactions. Molecules are generally able to move about in the plane of the membrane, giving the membrane its flexible nature called fluidity. Two other features of the membrane contribute to membrane fluidity: the chemical structure of the phospholipids and the presence of cholesterol in the membrane.

Asymmetric Lipid Bilayer01:35

Asymmetric Lipid Bilayer

7.2K
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%...

The Fluid Mosaic Model

144.8K
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.

Membrane Lipids01:32

Membrane Lipids

22.3K
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...

Area of Science:

  • Computational chemistry and molecular modeling
  • Drug discovery and development
  • Physical chemistry

Background:

  • Amphiphilicity is a key molecular property influencing drug formulation and self-assembly behavior.
  • Accurate quantification of amphiphilicity is essential for predicting molecular interactions and designing new therapeutics.
  • Existing simulation methods for amphiphilicity can be computationally intensive.

Purpose of the Study:

  • To introduce a general, computationally efficient atomistic model for quantifying molecular amphiphilicity.
  • To validate the model's accuracy against experimental surface tension data.
  • To investigate the influence of molecular structure on amphiphilicity and its correlation with partition coefficients.

Main Methods:

  • Development of a simplified fatty alcohol (dodecanol) membrane model.
  • Atomistic simulations of the dodecanol membrane interacting with various small molecules.
  • Comparison of simulation results with experimental surface tension measurements.
  • Analysis of the correlation between predicted amphiphilicity and water-octanol partition coefficients (logP).

Main Results:

  • The dodecanol membrane model accurately quantifies molecular amphiphilicity, showing good agreement with experimental surface tension data.
  • The model successfully elucidated the impact of different chemical motifs on amphiphilicity.
  • A strong correlation was observed between molecular amphiphilicity and logP values within the 0-4 range for 29 organic molecules.
  • Simulations using the fatty alcohol model were an order of magnitude faster than those using phospholipid membranes.

Conclusions:

  • The proposed fatty alcohol membrane model provides a rapid and accurate method for quantifying and predicting the amphiphilicity of small, drug-like molecules.
  • This approach offers a valuable tool for quantitative structure-activity relationship (QSAR) studies in drug discovery.
  • The model's efficiency makes it suitable for high-throughput screening and early-stage drug development pipelines.
