Many samples of rapeseed oil ethyl ester were prepared by alkaline-catalyzed transesterification at various conditions (reaction time, temperature, amount of catalyst, the molar ratio of ethanol to oil, the rotations of a disperser and the purification by water). The concentrations of the key impurities for biodiesel quality (the concentrations of monoglycerides, diglycerides, triglycerides, fr...

Commercially supplied radioiodinated triolein has been shown by thin-layer chromatography and silicic acid column chromatography to contain impurities, consisting mainly of diglycerides and monoglycerides, but also a small amount of free fatty acid. The effect of these impurities on the radioiodinated triolein absorption test requires further investigation.

Evaluation of four safflower (Carthamus tinctorius L.) genotypes for oil content and fatty acidcomposition showed that oil content varied from 22.16 to 34.39% and the highest seed oilcontent was obtained from Isfahan14 genotype (34.39%, respectively). Among those fatty acidswere detected, linoleic acid (75.81- 77.86%) was the predominant fatty acid followed by oleic(12.57–13.75%), palmitic (6.0...

LIPE is an intracellular neutral lipase, which is capable of hydrolyzing a variety of esters and plays a key role in the mobilization of fatty acids from diacylglycerols. The objectives of this study were to characterize the genetic polymorphism of bovine LIPE gene and to evaluate the possible association between three SNPs in the coding regions of this gene with the fatty acid composition of m...

abstract this experiment was conducted to study the effect of south-west climatic conditions on quantitative and qualitative of fatty acids in dog rose (rosa canina l.) seeds collected from five regions including: semirom (isfahan province), kiar and gerdbishe (charmahal and bakhtiari province), yasuj and meymand (kohgiluye and boyer ahmad province). oil was extracted using soxhlet apparatus; t...

nowadays, cardiovascular diseases are the most important cause of death. one of the reasons of cardiovascular diseases is poor nutrition, such as high intake of saturated fatty acids and low intake of essential and unsaturated fatty acids. among the oilseeds, flaxseed contains high amount of essential fatty acids, tochopherol, fiber and lignans. grape molasses is a traditional food in iran and ...

The effects of the use of essential oil of Rosmarinus officinalis on the chemical quality and fatty acids of fish fillets of Ctenopharyngodon idella were investigated during frozen storage at -18 ºC for 6 months. Fish fillets were divided into three groups; the control (C) without rosemary essential oil, the second group with 0.2 % rosemary essential oil (A) and the third with 0.4 % (v/v) rosem...

Fatty acid oxidation by washed intact ejaculated bull spermatozoa was depressed by carnitine concentrations as low as 5 mM, whereas oxygen uptake was only depressed by concentrations of 20 mM or above. Incorporation of (U-14C)-palmitate into 1,2-diglycerides was stimulated, and there was some stimulation of incorporation into phospholipids.
