Abstract This study investigated the effectiveness of foliar application sweet chestnut wood distillate on photosynthetic performance and growth lettuce ( Lactuca sativa L. cv ‘Canasta’), both alone in combination with soybean lecithin used as biosurfactant. Seedlings were treated a either mineral water (control), or 1:500 solutions 3% soy lecithin, plus lecithin. After 1 week, chlorophyll cont...

Lecithin or phospholipids is natural and widely used emulsifier. To improve its emulsifying properties, lecithin is modified by enzymatic hydrolysis using Phospholipase A1 (PLA1). PLA1 hydrolyzes at sn-1 position, that usually occupied by saturated fatty acids and more unsaturated fatty acid in lecithin is expected to increase hydrophilic properties. This study was aimed to investigate the hydr...

The solubilization of glucose and several related sugars in benzene solutions of rigorously purified phosphatidylcholine has been studied; the equilibrium degree of solubilization has been found to depend on the size of the sugar molecule relative to that of the lecithin micelle, and on the number and the acidity of its free hydroxyl groups. The uptake of glucose increased as the lecithin conce...

10,11-Didehydroquinine is a simple, low molecular weight supergelator which forms, in nonpolar media, stable chiral organogels composed of unique double-helix nano-sized fibers. A novel gelation mechanism involves a hydrogen bonding network formed by an acidic alkyne proton of the Cinchona gelator and the carbonyl group of ethyl acetate used as a solvent.

A 1,10-phenanthroline-appended cholesterol-based gelator (1) and its nongelling reference compound (2) were synthesized. Among 19 solvents tested herein, gelator 1 could gelate 11 solvents including alcohols, dipolar aprotic solvents, organic acids and a base (triethylamine), indicating that 1 acts as a versatile gelator. The TEM observation gave a visual image showing that fibrillar aggregates...

Symmetric oligothiophene derivatives containing hydrogen bond forming segments create self-supporting organogels consisting of self-assembled 1D nanostructures at low concentrations. Hydrogen bond formation and π-π stacking were both found to be crucial for the formation of conductive supramolecular networks of 1D nanostructures.

Tripeptide with redox active chemical entities based smart organogels have been used for in situ formation and stabilization of gold and silver nanoparticles within the supramolecular gel networks and the gold nanoparticles are aligned in arrays along the gel nanofibers of peptide 1-toluene gels.

Formation of organogels from covalently linked polyethylene glycols and cyclodextrins and their encapsulation/release properties were monitored with EPR spectroscopy using spin labels and spin probes; changes in molecular tumbling rates provided information on spin probe/label location inside the gel network, and molecular properties of the gel.

OBJECTIVE To assess the effects of soy isoflavone protein concentrate and soy lecithin on endothelial function, measured as flow-mediated dilation (FMD) of the brachial artery in healthy postmenopausal women. DESIGN This was a randomized, double-blind, placebo-controlled crossover trial with 25 participants (mean age, 61 years; body mass index, 25.46 kg/m2). The women underwent endothelial fu...

Cardiolipin antigens, used in the sero-diagnosis of syphilis, are mixtures of the phospholipids, cardiolipin, and purified natural lecithin (beefheart or egg), and usually also contain cholesterol. In 1949 Baer and Kates (1949, 1950) succeeded in the synthesis of L-ac-dimyristoyl lecithin and in the following years other types of synthetic lecithin were produced, including a D-oc-dimyristoyl le...
