We have studied the lipid composition and the acyl group composition, transport, and metabolism of doxorubicin-sensitive and -resistant rat glioblastoma cells in monolayer cultures (C6 clone). No difference in lipid composition was evidenced; the acyl group composition was, in contrast, highly modified in resistant cells, and these modifications appeared progressively during the acquisition of ...

Introduction Gamma-linolenic acid (GLA) is an important conditionally essential fatty acid (EFA). GLA is an omega-6 polyunsaturated fatty acid (PUFA). The fatty acid molecule is comprised of 18 carbon atoms with three double bonds. It is also known as 18:3n-6; 6,9,12-octadecatrienoic acid; cis-6, cis-9, cis-12octadecatrienoic acid; and gamolenic acid. GLA is found naturally in the fatty acid fr...

In humans, the polyunsaturated fatty acids (PUFA) linoleic acid (18:2 omega-6, or n-6) and alpha-linolenic (18:3 omega-3, or n3) are ’essential’ for normal growth and function; the only source is dietary. Research into the omega-3 series of essential polyunsaturated fatty acids stems from the observation that the native Inuit (Eskimo) of Greenland (who consume a traditional diet rich in fish oi...

ABSTRACT: Degumming and neutralization processes are two essential stages carried out on crude edible oils in order to remove some unwanted impurities namely gums and free fatty acids. In this research study two popular less expensive commercial oils that are consumed to a great extent namely soyabean and sunflower seed oils are selected and subjected to both degumming and neutralization proces...

Purpose: Suitable ratio of essential fatty acids has an important role in maintaining good health. There is no pure oil with an ideal fatty acid composition and oxidative stability. The main goal of the present study was to evaluate the physical, chemical and nutritional properties of oil obtained by blending flaxseed oil as a rich source of ω3 fatty acids with sesame and olive oils. Methods: T...

Dietary sources of the essential fatty acid a-linolenic acid (ALA; 18:3n-3) include green leaves, some seeds, nuts and cooking oils. The principal dietary source of the long-chain (LC) n-3 polyunsaturated fatty acids (PUFA) eicosapentaenoic acid (EPA; 20:5n-3), docosapentaenoic acid (DPA; 22:5n-3) and docosahexaenoic acid (DHA; 22:6n-3) is oily fish, yet it is estimated that only 27% of UKadult...

The mammary gland is one of the few adult tissues that strongly induce de novo fatty acid synthesis upon physiological stimulation, suggesting that fatty acid is important for milk production during lactation. The committed enzyme to perform this function is fatty acid synthase (FASN). To determine whether de novo fatty acid synthesis is obligatory or dietary fat is sufficient for mammary gland...

abstract         background and objective: the relationship between diabetes mellitus and increased risk of cardiovascular diseases has been demonstrated. the aim of this study was to determine the fatty acid profile of epicardial adipose tissue in diabetic and non-diabetic patients with cardiovascular disease.          methods: in this study, 28 diabetic and 40 nondiabetic patients were evalua...
