The aim of the present study was to assess the effect of slaughter and carcass weight, age at slaughter and sex on the fatty acid profile of the Greek Boutsiko sheep breed. Twenty lambs (ten females and ten males) were examined. The lambs were slaughtered at the age of 48 days. Carcasses were chopped in nine specific cuts and a random sample of 100 g was taken from each cut, with a total of 180...

What are trans fatty acids (TFA)? Fatty acids found in foods can be saturated (SFA, no double bonds), monounsaturated (MUFA, 1 double bond) or polyunsaturated (PUFA , 2 or more double bonds). The double bonds provide rigidity to the molecule and result in specific molecular configurations. Naturally occurring fatty acids in foods usually have the cis configuration, i.e. the hydrogen atoms with ...

The technique of gas-liquid chromatography-chemical ionization mass spectrometry can easily identify trace peaks and unresolved peaks on gas-liquid chromatography, utilizing MH(+) ions of chemical ionization mass spectra. In polyunsaturated fatty acid methyl esters such as C22:5 and C22:6, the determination of molecular weights that are difficult to determine by electron impact mass spectrometr...

The changes in lipid and fatty acid contents after soaking, cooking, germination and fermentation of three white sorghum varieties were studied to improve cereal quality. The results revealed that oil in raw sorghum varieties ranged from 3.58 to 3.91%, respectively and ‘Dorado’ represents the highest variety in oil content. As general trend after germination, oil content was decreased. Fatty ac...

For a long time, the perception of consumers about fat from animal origin was linked to the increased risk of cardiovascular diseases, especially due to the large amounts of saturated fatty acids. The dairy products provide 15 to 25% of fat consumed by humans and 25 to 35% of saturated fat (Chilliard et al., 2001). This statement of cognizance, even if the potential effects of saturated fatty a...

Most studies on lipid lowering diets have focused on the total content of saturated, polyunsaturated and monounsaturated fatty acids. However, the distribution of these fatty acids on the triacylglycerol (TAG) molecule and the molecular TAG species generated by this stereospecificity are characteristic for various native dietary TAGs. Fat randomization or interesterification is a process involv...

Abnormal HDL metabolism among patients with diabetes and insulin resistance may contribute to their increased risk of atherosclerosis. ATP binding cassette transporter A1 (ABCA1) mediates the transport of cholesterol and phospholipids from cells to HDL apolipoproteins and thus modulates HDL levels and atherogenesis. Because fatty acids are increased in diabetes, we examined their effects on ABC...

Several studies indicate that frequent nut intake (a serving per day, of ~28 to 100 g/d) confers protective effects against cardiovascular disease. In general, nuts have high lipid contents but with favorable profiles for promoting cardiovascular health, since they are low in saturated fatty acids and high in mono and polyunsaturated fatty acids. Studies connecting nut consumption and cardiovas...

OBJECTIVE Low-density lipoprotein receptor-related protein 1 (LRP1) is a multifunctional endocytic receptor that is highly expressed in adipocytes and the hypothalamus. Animal models and in vitro studies support a role for LRP1 in adipocyte metabolism and leptin signaling, but genetic polymorphisms have not been evaluated for obesity in people. DESIGN AND METHODS We examined whether dietary f...
