Matrix Effect in Oleate Micelles-Vesicles Transformation

Solubilization of triolein and cholesteryl oleate in egg phosphatidylcholine vesicles.

The incorporation of cholesteryl oleate and triolein into phospholipid vesicles was studied in cosonicated mixtures of 94 weight % egg phosphatidylcholine and 6 weight % neutral lipid (0-6% triolein and 6-0% cholesteryl oleate). 13C NMR spectroscopy was used to quantitate both neutral lipids in vesicles containing 90% isotopically substituted [carbonyl-13C]cholesteryl oleate and [carbonyl-13C]t...

Spontaneous transformation from micelles to vesicles associated with sequential conversions of comprising amphiphiles within assemblies.

A morphological transformation from hybrid micelles to giant vesicles was observed in aqueous dispersion associated with formation of a double-chained amphiphile as a result of the migration of dodecylamine from the amphiphilic imine to the amphiphilic aldehyde within the hydrophobic environment of amphiphilic aggregates.

Formation and stability of micelles and vesicles

Matrix vesicles and calcification.

Matrix vesicles (MVs) are extracellular, 100 nM in diameter, membrane-invested particles selectively located at sites of initial calcification in cartilage, bone, and predentin. The first crystals of apatitic bone mineral are formed within MVs close to the inner surfaces of their investing membranes. Matrix vesicle biogenesis occurs by polarized budding and pinching-off of vesicles from specifi...

Glyco-Inside Micelles and Vesicles Directed by Protection− Deprotection Chemistry

Protection−deprotection of carbohydrate is often required in the preparation of glycopolymers, which causes an obvious polarity change of the polymers, but it has been neglected in the studies of self-assembly. In this paper, a new strategy for self-assembly of sugar-containing block copolymers is suggested based on the protection−deprotection chemistry. We found that deacetylation of a series ...
