Lipids are a group of naturally occurring compounds and hydrophobic or amphiphilic molecules that form structures such as vesicles, liposomes or membranes in an aqueous environment. They are a large and diverse group of organic macromolecules; hence, it is always difficult for scientists to provide a specific definition for the word “lipid”. Therefore, due to the absence of a widely-accepted de...

The oil from seeds of 4 pea nut (Arachis hypogaea L.) varieties: Golden, Bari 2000, Mongphalla, and Mongphalli 334 cultivated in arid zones, was subjected to the comparative evaluation of its physicochemical properties, fatty acid profile and antioxidant activity. Pea nut seeds were found to be a rich source of crude fat (45.09-51.63 g/100 g dry weight). The physicochemical properties of the oi...

There has been an increasing interest in the measurement of carotenoids, retinoids, and tocopherols in human tissues because some of these micronutrients have been shown to have chemopreventive activity. Since clinical tissue samples obtained for analysis are usually small in quantity, a sensitive analytical procedure that can simultaneously measure all the micronutrients of interest in one sma...

Lysophosphatidylcholine is an abundant component of plasma and oxidized LDL that displays several biological activities, some of which may occur through the platelet-activating factor (PAF) receptor. We find that commercial lysophosphatidylcholine, its alkyl homolog (lyso-PAF), and PAF all induce inflammation in a murine model of pleurisy. Hydrolysis of PAF to lyso-PAF by recombinant PAF acetyl...

The crude wax obtained from the chloroform extract of the human type of tubercle bacillus, Strain H-37, yielded on purification, as described in a former paper (l), two fractions; viz., a white solid substance designated as purified wax and a soft yellowish salve-like mass which was called soft wax. The present report deals with the analysis of the latter fraction. The work is far from complete...
