It has been recognized for some years that lecithin is an internally neutralized compound (1). The neutralization takes place between a strongly acidic group and a strongly basic group. Solutions of lecithin therefore may be expected to show no buffering power within the physiological range and this has been observed to be the case (24). The internal neutralization of lecithin has led to the pr...

INTRODUCTION We report previously unpublished, early pilot studies performed with a brain-health food supplement containing a proprietary blend of 100 mg phosphatidylserine (PS) and 80 mg phosphatidic acid (PA) produced from soy lecithin. METHODS Serum analysis after single PS+PA ingestion was performed in healthy volunteers. A 3-month double-blind, placebo-controlled study assessed the influ...

training, a young Serge Gauthier found himself up to his elbows in lecithin. His sleeves rolled up and his arms buried deep in big barrels of imported lecithin, he and his mentor, Dr. Pierre Etienne, scooped up kilos and kilos of the phospholipid like market merchants and handed it over to the families of patients with Alzheimer’s disease (AD). The two researchers hoped that with regular lecith...

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...
