antioxidant active packaging is one of the active packaging that prevents of lipid oxidation by releasing antioxidant during storage of food. in recent years the use of natural antioxidant instead of the synthetic variety in these packaging has been considered. the aim of this study was evaluating the performance of polymeric film coated with natural antioxidant (rosemary extract) to prevent li...

Bile duct ligation was performed in germ-free and conventional rats in order to study the effects of bile deprivation on the absorption of dietary lipids and the excretion of faecal lipids in the presence or the absence of gastrointestinal flora. The main consequence of bile duct ligation in conventional rats was decrease of about 50% in the apparent absorption of dietary lipids (peanut oil). I...

The lipids of rat milk, the contents of 9-- 10-day-old rat stomach and intestine, lymph, plasma, and liver were quantitated and their fatty acids were analyzed. Rat milk consists of 97% triacylglycerols, of which 35% of the fatty acids are of medium chain length (C8-C12). However, stomach triacylglycerols show a 25% reduction in medium chain fatty acids, which indicates preferential hydrolysis ...

Aminoacyl-tRNA synthetases from higher eukaryotes often are isolated as high molecular weight complexes associated with other components such as lipids. Since hydrophobic interactions are involved in the organization of the complex, it has been suggested that interaction of synthetases with these lipids might be important for their structure and function. Delipidation is known to affect certain...

The acyl pattern of adipose tissue triglycerides and of plasma free fatty acids were determined after 7 yr of diet intervention on elevated plasma cholesterol in 42 men taking part in the smoking-lipid trial of the Oslo Study. Twenty-two of the men were advised to change dietary habits (mainly reduce saturated fat) whereas the remaining 20 were controls. The adipose tissue from men in the inter...

Background Background: The fatty acid composition of the sperm membrane changes drastically during spermatogenesis and may be key to its function. Previous data has shown that intake of long chain poly-unsaturated fatty acids can change the fatty acid composition of tissues, including testes and sperm. However, whether these changes in composition translate into changes in semen quality or male...
