A series of chiral aryl amide compounds bearing peptide pendants have been investigated as low molecular weight gelators. A mechanistic study reveals that complementary hydrogen bonding from peptide pendants is the main driving force for the formation of organogels. This new class of organogels can exhibit multi-stimuli-responsive behavior upon applying (1) thermal, (2) pH, (3) enantiomeric pur...

A new organogelator, benzyl (4-methyl-1-oxo-1-(2-hexadecanoylhydrazinyl)pentan-2-yl)carbamate (designated as Cbz-Leu-HdHz), was designed and synthesized, which could self-assemble in many organic solvents and form the thermally reversible physical supramolecular organogels. The gel-sol phase transition temperatures (TGS) were determined as a function of gelator concentration and the correspondi...

Three isomeric pyridine-containing L-glutamic lipids formed organogels in DMSO and self-assembled into different nanostructures of nanofiber, nanotwist and nanotube depending on the substituent position in the pyridine ring.

Incorporation of dietary phospholipids into lymph chylomicrons was studied in rats fed corn oil containing either radioactive lecithin or lysolecithin. The specific activity of lecithin-s2P in chylomicrons relative to that in the oil increased directly with the amount of lecithin fed, whereas the lecithin content of chylomicrons was constant. About 40% of the phospholipid in chylomicrons was de...

Lecithin, a naturally small molecular surfactant, which is widely used in the food industry, can delay aging, enhance memory, prevent and treat diabetes. The interaction between zein and soy lecithin with different mass ratios (20:1, 10:1, 5:1, 3:1, 2:1, 1:1 and 1:2) in ethanol-water solution and characterisation of zein and lecithin composite colloidal nanoparticles prepared by antisolvent co-...

The purpose of this review is to give an insight into the considerable potential of lecithin based nanocarriers. The lecithin microemulsion and closely related microemulsion based systems are currently of interest to pharmaceutical researchers. Conventional systems for topical delivery of drugs meet many hindrances like reduced permeation and entrapment efficiency. Lecithin nanocarriers with th...

A biscalix[4]arene ( capable of spontaneous self-assembly into nanoparticles and microspheres in CH3CN was serendipitously observed, and it eventually formed stable blue-light emitting supramolecular organogels.

Short-chain ceramides, such as N-acetoyl-d-erythro-sphingosine (C2), have a remarkable ability to structure edible oils, such as canola oil, into self-standing organogels without any added saturated or trans fats. These short-chain ceramides are ubiquitously found in foods ranging from eggs to soybeans. As the ceramide fatty acid chain length increases, there is an increase in the melting tempe...
