The effects of frying unripe plantain and sweet potato (separately) in soyabean oil on the properties of the oil were investigated. Also, the effect of the degradation of the oil on biodiesel yield obtained from the oil was considered. Physico-chemical properties of soyabean oil (acid value, saponification value, viscosity, density, colour) were measured daily after being used for frying for da...

Cholesterol has been used to monitor artifact generation. Stability differences among cholesterol oxide products (COPs) and cholesterol in thermal and alkaline conditions are theorized. Thus, use of cholesterol may be unsuitable for detection of artifacts generated from COPs. Stability of cholesterol was compared to that of 7-ketocholesterol (7-keto) and β-sitosterol (βS) under various thermal ...

The study reports the alternative use of non-edible fermented olives for production high-quality natural soaps with a fast process, low environmental impact, and without preliminary treatments raw material. Damaged olives, not used as food, were naturally oil was extracted by mechanical extraction. product obtained human consumption due to its high acidity, but it had content peroxides. olive a...

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...

By way of introduction a brief summary of the conclusions of a previous communication1 may be given. Strophanthidin and all of its derivatives which possess both the la&one group and the double bond of the parent substance reduce Tollens’ reagent and also give a positive nitroprusside reaction. The same has been found to be true of ouabain, gitoxin, and digitoxin. On saponification or hydrogena...

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...
