Lipids triglyceride

C2-C4 w-alkanes [42,43], and in supercritical carbon dioxide when employing novel surfactants with fluorocarbon tails [38,44], There is also interest in the further employment of lipids (triglycerides and wax esters, such as isopropyl myristate) as solvent to improve biocompatibility [45],... 

Fatty acids are key constituents of several structural classes of lipids triglycerides, glycerophospholipids, and glycolipids. 

Lipid metabolism. Oil, administered orally to female C57BL/6 mice weaned at 21 d of age at a dose of 15% w/w for 6 weeks, increased the total lipids, triglycerides, LDL and VLDL cholesterol, and thioharhituric acid-reactive substances (TEARS) and reduced glutathione concentrations, without changes in phospholipids or total cho-...

The observations on the aromas from cysteine + ribose reaction mixtures have been extended to compare the effect of different lipids triglycerides and phospholipids extracted from beef, and commercial egg lecithin (phosphatidylcholine) and egg cephalin (phosphatidylethanolamine) (L.J. Salter D.S Mottram, unpublished data). The inclusion of the beef triglycerides (TG) did not appear to have any effect on the aroma of the cysteine + ribose reaction mixture, which was sulfurous with an underlying meatiness. However, when beef phospholipids (FL) were used the meaty aroma increased markedly. Similarily, addition of egg lecithin (LEC) or egg cephalin (CEPH) to the cysteine + ribose reaction mixture gave increased meatiness, with the cephalin-containing mixture being judged to have the most meaty character. 

Inulin and fructooligosaccharides are more effective at lowering serum levels of lipids (triglycerides) than cholesterol, with inulin more effective than short-chain fructooligosaccharides in... 

Fig. 1. General oil-droplet model of lipoproteins is presented for chylomicron, very low-density lipoprotein (VLDL), low-density lipoprotein (LDL), and high-density lipoprotein (HDL) structures. Apolipoproteins in the outer phospholipid membrane, designated by letters, are defined in Table II. The major differences between the lipoproteins are the size of the neutral lipid (triglyceride and esterified cholesterol) core, liquid composition in the core, and apolipoprotein composition. (E) Triglycerides, ( Q ) phospholipids, and ( -) esterified cholesterol are shown. Although not shown, unesterified cholesterol is found predominantly in the phospholipid monolayer.

Implanted polymeric materials can also adsorb and absorb from the body various chemicals that could also effect the properties of the polymer. Lipids (triglycerides, fatty acids, cholesterol, etc.) could act as plasticizers for some polymers and change their physical properties. Lipid absorption has been suggested to increase the degradation of silicone rubbers in heart valves (13). but this does not appear to be a factor in nonvascular Implants. Poly(dimethylsiloxane) shows very little tensile strength loss after 17 months of implantation (16). Adsorbed proteins, or other materials, can modify the interactions of the body with the polymer this effect has been observed with various plasma proteins and with heparin in connection with blood compatibility. 

Energy storage. Most of the energy stored in the body is in the form of lipids (triglycerides). Stored in fat cells called adipocytes, these fats are a particularly rich source of energy for the body. 

Dietary lipids (triglycerides) are emulsified into tiny fat droplets in the intestine by the action of bile salts. Pancreatic lipase catalyzes the hydrolysis of triglycerides into monoglycerides and fatty acids. These are absorbed by intestinal epithelial cells, reassembled into triglycerides, and combined with protein to form chylomicrons. Chylomicrons are transported to the cells of the body through the bloodstream. Fatty acids are stored as triglycerides (triacylglyc-erols) in fat droplets in the cytoplasm of adipocytes. 

Enzymes are named for what they do. As an example, lipase enzymes cause lipid triglycerides to dissolve and form glycerol and fatty acids. 

In this book, a large number of biomaterials are reported. These include polypeptides/proteins, carbohydrates, lipids/triglycerides and synthetic polymers. In addition, it is understood that many of the polymeric materials involved in all the chapters can potentially be used as biomaterials although they may not be specified as such. 

Serum lipid concentrations vary during the menstrud cycle with serum cholesterol and phospholipid minimal at approximately the time of ovulation [227]. Serum lipids, triglycerides and cholesterol increase during pregnancy concomitantly with increased placental oestrogen synthesis [228, 229].
