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...

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...

Lecithin has been found to interfere with the combining reaction of Cl. welchii alpha toxin (lecithinase) and its antitoxin. If the lecithinase is first brought into contact with lecithin, and the antitoxin is then added, the antitoxin fails to stop the enzymatic reaction, but gradually decelerates it. If the lecithinase is brought into contact with both lecithin and antitoxin at the same insta...

Forty crossbred (Large White × Landrace × Duroc) female pigs (16.4 kg ± 0.94 kg) were used to investigate the effect of dietary lecithin supplementation on growth performance and pork quality. Pigs were randomly allocated to a commercial diet containing either 0, 3, 15 or 75 g lecithin/kg of feed during the grower and finisher growth phase. Pork from pigs consuming the diets containing 15 g and...

Despite its importance in cholesterol gallstone formation, crystallization of cholesterol from bile is poorly understood, especially with respect to the influences of other biliary lipids. We reported recently (Konikoff et al. J. Clin. Invest. 1992. 90: 1155-1160) that cholesterol can crystallize from model and native biles as filamentous crystals covered by a surface layer of lecithin molecule...

Recent studies suggest that lecithin-rich diet can modify cholesterol homeostasis and hepatic lipoprotein metabolism. Considering the phytotherapeutic impact of lecithin, this work hypothesizes that lecithin administration in hypercholesterolemic patients may reduce cholesterol concentrations by increasing biliary secretion. Total cholesterol and LDL were evaluated after soy lecithin administra...
