Purpose: To investigate the physicochemical properties and DPPH radical scavenging activity of gallic acid–lecithin complex Methods: The complex of gallic acid with lecithin was prepared by solvent method. The physicochemical properties of the complex were investigated by ultraviolet-visible spectrometry (UV), infrared spectrometry (IR), scanning electron microscopy (SEM), differential scanning...

The initial rate of lecithin: cholesterol acyl transferase and serum concentration of lipids were determined in euthyroid, hypothyroid and hyperthyroid subjects. In hyperthyroid subjects, the serum levels of total and free cholesterol were significantly lower than in normal subjects and the fractional lecithin: cholesterol acyl transfer rate was significantly higher than in normal subjects. The...

We compared seven techniques, commonly used for detection of amniotic fluid phospholipids in thin-layer chromatography, with respect to their sensitivity to saturation of the fatty acid carbon-chain of lecithin. The techniques fell into two classes: sensitive and insensitive; those classed as saturation sensitive were less than or equal to 10% as sensitive to fully saturated lecithin as to leci...

the aim of this study was to determine the effect of low levels of glutathione on post-thawed buck sperm quality. in this experiment, different concentrations of glutathione [0 (lg-0), 0.5 (lg-0.5), 1 (lg-1), 1.5 (lg-1.5), and 2 (lg-2) mm] were added in a soybean lecithin-based extender. a total of 16 ejaculates from four bucks were collected and pooled. each pooled sample was divided into five...

1. We have studied the plasma lipoprotein abnormalities in obstructive jaundice to test the hypothesis that the abnormalities would correlate with plasma lecithin--cholesterol acyltransferase activity. 2. Very-low-density lipoproteins (VLDL) were normal in composition and had a normal pre-beta electrophoretic mobility when lecithin--cholesterol acyltransferase activity was high. When it was low...

In the course of W-tracer studies on the biological synthesis of lecithin in lung tissue slices, the ratio of fatty acid activity to glycerol activity in lecithin was higher than in the triglyceride fraction. It was suggested that the observed isotope distributions could be due to turnover of the fatty acid portion of lecithin without a corresponding synthesis and breakdown of the remainder of ...

Recently, increasing attention has been paid to lecithin/chitosan nanoparticles as colloidal drug delivery system showing the great potential to improve the permeation of encapsulated drug across various biological barriers [1, 2]. However, the overall poor stability of colloidal nanoparticles in an aqueous medium is a significant drawback in their development perspective. Therefore, the aim of...

The lecithin which is used in cardiolipin antigens for the sero-diagnosis of syphilis is extracted from beef heart tissue or egg yolk by the methods of Pangborn, Maltaner, Tompkins, Beecher, Thompson, and Flynn (1951). The product is actually a mixture of individual lecithins containing chiefly unsaturated but also some saturated fatty acids, the composition varying with the source and method o...

The incorporation of [2-3H]glycerol and lysolecithin labeled with [2-3H]glycerol into lecithin and its subspecies was investigated in epithelial and muscular layers of rat small intestine. The labeled compounds were administered in two wways: the intraduodenal injection and the injection into femoral vein. The incorporation of glycerol into lecithin was distinctly higher in epithelial layer tha...

Lecithin was fi rst isolated from egg yolk in the 1850’s. The Greek word for egg yolk, lekithos, is the basis for the name lecithin. Lecithin has a reputation for being “brain food” because of its high concentration of phosphatidyl choline, a nutrient which supports primary brain functions including memory, thought, and muscular control. Phosphatidyl choline is the biological precursor to acety...
