Spontaneous vesicles formed from hydroxide surfactants: evidence from electron microscopy
Summary
Dialkyldimethylammonium hydroxide surfactants form stable, water-soluble vesicles ideal for studying membrane fusion and ion transport. These systems offer a unique model, differing from insoluble surfactant phases.
Area of Science:
- Colloid and Surface Science
- Supramolecular Chemistry
- Biophysical Chemistry
Background:
- Dialkyldimethylammonium hydroxide surfactants exhibit high water solubility.
- These surfactants spontaneously form stable vesicle structures in aqueous solutions.
- Vesicle size can be controlled by the addition of acid.
Purpose of the Study:
- To investigate the properties of dialkyldimethylammonium hydroxide surfactant vesicles.
- To establish these vesicles as a membrane mimetic system for studying fusion and ion transport.
- To explore the role of hydration forces in surfactant self-assembly and behavior.
Main Methods:
- Characterization of surfactant vesicle formation and stability.
- Investigation of vesicle size control mechanisms.
- Analysis of hydration forces influencing surfactant systems.
Main Results:
- Spontaneous formation of stable, water-soluble vesicles by dialkyldimethylammonium hydroxide surfactants.

Micelles
Micelle formation is an intricate process that hinges on the properties of amphiphilic or amphipathic molecules and the conditions of the system in which they are found. Amphiphilic molecules, which have both hydrophilic (water-attracting) and hydrophobic (water-repelling) parts, play a critical role in this process.In aqueous environments, these molecules arrange themselves such that their hydrophilic heads are turned towards the water phase, while their hydrophobic tails are oriented away...
Intralumenal Vesicles and Multivesicular Bodies
Intraluminal vesicles (ILVs) are small vesicles 50-80 nm in diameter formed during the maturation of early endosomes. A specialized endosome containing numerous ILVs is called a multivesicular body (MVB). ILVs contain internalized molecules such as antigens, nucleic acids, proteins, and metabolites. Some of these molecules are released from the MVBs inside exosomes and are transported to other cells. Other MVBs contain molecules that are retained in the ILVs and are later degraded within the...
COP Coated Vesicles
Membrane-enclosed structures called vesicles transport proteins and lipids across the cell. The vesicles derive their cargo from the plasma membrane, Golgi, ER, or endosome. Coated vesicles are spherical, protein-coated carriers with a 50–100 nm diameter that mediate bidirectional transport between the ER and the Golgi. The distribution of proteins between the ER and Golgi complex is dynamic and is maintained by different coated vesicles. Their formation is driven by the assembly of different...
Pinching-off of Coated Vesicles
Vesicle budding is orchestrated by distinct cytosolic proteins such as adaptor proteins, coat proteins, and GTPases. To initiate vesicle budding, membrane-bending proteins containing crescent-shaped BAR domains bind to the lipid heads in the bilayer and distort the membrane to form a protein-coated vesicle bud. Adaptors proteins such as AP2 for clathrin-coated vesicles can nucleate on the deformed membrane. Finally, coat proteins such as clathrin or COPI and COPII assemble into a coat forming...
Overview of Secretory Vesicles
Secretory vesicles, also known as dense core vesicles (DCVs), are membrane-bound vesicles that transport secretory proteins, such as hormones or neurotransmitters. Regulated secretory vesicles transport proteins from the trans-Golgi network to the exterior of the cell. Proteins present in regulated secretory vesicles are required to be rapidly exocytosed in large amounts upon a specific stimulus.
Various proteins regulate the aggregation of molecules inside the secretory vesicles. Chromogranins...

Colloids
Children at play often make suspensions such as mixtures of mud and water, flour and water, or a suspension of solid pigments in water known as tempera paint. These suspensions are heterogeneous mixtures composed of relatively large particles that are visible to the naked eye or can be seen with a magnifying glass. They are cloudy, and the suspended particles settle out after mixing. On the other hand, a solution is a homogeneous mixture in which no settling occurs and in which the dissolved...
