Based on their chemical nature, the fatty acids are broadly grouped as saturated, monounsaturated and polyunsaturated. Available data suggests that 100 g of lard (pig fat) contains: . Saturated fatty acids increase LDL cholesterol levels in the body. plaques and properties of physical saturated fatty acids called embryos continuously form. The desaturase introduces a double bond into 16-chain and 18-chain saturated fatty acids which, if expressed in the seeds, the saturated fatty acid content of the oil could be reduced (7). at room temperature liquid, saturated C 18 fatty acid. Methods and results In wild-type mice, 16-weeks SFA-rich high lard diet feeding (HLD) caused activation of PPARα signaling and the accumulation of toxic lipid intermediates (diacylglycerol and ceramide) in the heart to the same extent as a MUFA-rich high olive . Rats were fed a high starch (STD), high sucrose (HSD), high polyunsaturated fat (HPUF) or high saturated fat (HSAT) diet for 4 or 24 weeks. Palmitic acid is a saturated fatty acid present in the three samples in a small proportion. 12. Some of these saturated fatty acids are 23.8 g of Palmitic Acid (PAL), 13.5 g of Stearic Acid (SA), 1.3 g of Myristic Acid (MA) and 0.2 g of Lauric Acid (LAA). In a cross-sectional population study of >4,000 healthy individuals, fasting insulin concentration was positively associated with the percentage of saturated fat and inversely associated with the percentage of monounsaturated fat in plasma phospholipids (). Fatty acids have important roles in: 1) signal-transduction pathways; 2) cellular fuel sources; 3) the composition of hormones and lipids; 4) the modification of proteins; and 5) energy storage within adipose tissue . Large amount of saturated fatty acids (SFA) was found in freshwater eel oil, with lauric acid and palmitic acid as predominant fatty acid.

The structure of fatty compounds affects the properties of biodiesel in terms of density, cetane number, calorific value . For example, replacing saturated fats with unsaturated fatty acids in the diet is . 50. An increase in dietary fat increases hepatic fat in both normal weight (6-8) and obese (9,10) individuals.As hepatic fat content may be a driver of the metabolic syndrome (11,12), an interesting feature of this trial is that the change in liver fat was strongly related to SFA, but not to similar levels of PUFA.Previously, the same group showed that PUFA decreased liver fat in normal weight . It is one of the most common saturated fatty acid found in butter, . In pork, saturated fatty acids are preferred to the unsaturated fatty acids, as they are more oxidatively stable. Conclusions: The proportional saturated fatty acid composition of plasma is positively associated with the development of diabetes. In biochemistry, fatty acid synthesis is the creation of fatty acids from acetyl-CoA and NADPH through the action of enzymes called fatty acid synthases.This process takes place in the cytoplasm of the cell.Most of the acetyl-CoA which is converted into fatty acids is derived from carbohydrates via the glycolytic pathway.The glycolytic pathway also provides the glycerol with which three fatty .
