The kinetics of dissolution of dispersions of egg phosphatidylcholine (lecithin) by bile salts was studied by observing the decrease in turbidity as mixed micelles of lecithin and bile salt were formed. The rate of dissolution of lecithin corresponding to the formation of mixed micelles was studied in the presence of dihydroxy bile salts, sodium deoxycholate, sodium chenodeoxycholate, sodium ur...

A method to quick detect concentration of lecithin in eggs, namely microwave digestion spectrophotometry, was established in this research. The homogenate of eggs was treated with absolute ethanol to eliminate phosphate protein in eggs which could possibly affect concentration of lecithin examined. A sample then received a new way of pre-treatment, called microwave digestion, before UV-Vis ...

In this study, the effects of dietary chicken egg lecithin on some blood biochemical factors of Mesopotamichthys sharpeyi juveniles and resistance to thermal shock was investigated. Juveniles with initial average weight of 3.10±0.17 were stocked in 12 fiberglass tanks. Four isolipidic and isonitrogenic diets containing 0% (control), 2%, 4% and 6% chicken egg lecithin were used to feed the fish ...

BACKGROUND Previous studies have shown that plasma and urinary free choline concentrations decrease significantly during a marathon, and that these decreases may be associated with decreased performance. OBJECTIVE In a pilot study, we sought to determine whether lecithin supplementation prior to a marathon would maintain plasma free and urinary choline concentrations and improve performance v...

1. The soluble phospholipase D of cabbage was purified by heat treatment, acetone precipitation and electrophoresis on a density gradient of aqueous glycerol. 2. The purified enzyme slowly attacked a lecithin suspension whereas ultrasonically treated lecithin was hydrolysed more rapidly. 3. Diethyl ether stimulated the hydrolysis of both the lecithin suspension and ultrasonically treated lecith...

Introduction: Astaxanthin, a highly active oxidant, possesses potential effect on human health. However, with the oily characteristic, ability to disperse in an aqueous environment has limited its application. Therefore, aim of this study is fabrication stable astaxanthin emulsion water. Methods: In study, was fabricated using polysorbate (tween 60/80) or lecithin. The dispersing methods magnet...

A rapid and accurate single step procedure is described for the assay of lecithin-cholesterol acyltransferase activity. After incubation, using radiolabeled cholesterol as the substrate, an ethanolic solution of digitonin is added directly to the incubation mixture to extract the lipids. Excess cholesterol is then added, and the labeled cholesterol-digitonide along with denatured proteins are s...

1. The hypodermic administration of tethelin increases markedly the rate of growth of the primary tumor and the tendency to form metastases in rats inoculated with carcinoma, in this, as in other respects, reproducing the action of the whole anterior lobe of the pituitary body. 2. Other alcohol-soluble extractives of the anterior lobe of the pituitary body, with the exception of the lecithin fr...

Four patients with Friedreich's ataxia took part in an open trial, in which they consumed 50-100g/day lecithin granules (containing approximately 22% phosphatidycholine) for 16 weeks, but no improvement resulted. Several unwanted effects including diarrhoea, nausea, depression, "hot flushes" and weakness were experienced. Resting levels of free-choline in plasma were within the range found in 1...
