Glycerides fatty acids

Molecular Interactions. Various polysaccharides readily associate with other substances, including bile acids and cholesterol, proteins, small organic molecules, inorganic salts, and ions. Anionic polysaccharides form salts and chelate complexes with cations some neutral polysaccharides form complexes with inorganic salts and some interactions are stmcture specific. Starch amylose and the linear branches of amylopectin form inclusion complexes with several classes of polar molecules, including fatty acids, glycerides, alcohols, esters, ketones, and iodine/iodide. The absorbed molecule occupies the cavity of the amylose helix, which has the capacity to expand somewhat to accommodate larger molecules. The starch—Hpid complex is important in food systems. Whether similar inclusion complexes can form with any of the dietary fiber components is not known. 

Lipids in living systems are by solvents extractable compounds. Among the lipids are the fatty acids, glycerides, steroids, terpenes, and complex lipids as lipoproteins.

A controversial problem is still the selection of suitable enhancing agents to overcome the often limited absorption from the colon. In a survey a number of commonly used enhancers, bile salts, surfactants, fatty acids, glycerides, etc. were also reported as effective in the colon [86],... 

Glyceryl Behenate occurs as a fine powder. It is a mixture of fatty acid glycerides, primarily glyceryl esters of behenic acid, that melts at about 70°. It is soluble in chloroform and practically insoluble in water and in alcohol. 

Vegetable oil refinery lipid, feed grade (33.7), is obtained in the alkaline refining of a vegetable oil for edible use. It consists predominantly of the salts of fatty acids, glycerides, and phosphates. It may contain water and not more than 22% ash on a water-free basis. It is to be neutralized with acid before use in commercial feed. Includes IFN 4-05-078 (vegetable oil refinery lipid). 

Olive oil is a mixture of fatty acid glycerides. Analysis of olive oil shows a high proportion of unsaturated fatty acids, and a typical analysis shows that the composition of the fatty acids is as follows ... 

Gunstone ct found that separation of saturated and unsaturated fatty acid glycerides by crystallization at -10° is improved by addition of silver nitrate in methanol to complex with the unsaturated components. Morris reports separation of CIS and trans fatty acids and oxygenated fatty acids by thin-layer chromatography on silica gel impregnated with silver nitrate. With untreated silica there was no separation.

Highly nonpolar compounds such as fatty acids, glycerides, alkanes, and some lower terpenoids require simple nonpolar solvent systems (e.g., cyclohexane, hexane, pentane, diethyl ether.hexane mixtures) and may be difficult to detect by UV (i.e., no chromophore) or by spray detection (use charring reagents, e.g., vanillin-sulfuric acid). 

Lipids are one of the major structural components in living cells and encompass a myriad different types of compound. In most cases, they possess only one common property, which is their solubility in non-polar solvents such as chloroform, ether, hydrocarbons or alcohols and insolubility in water (Davenport and Johnson, 1971). Some of the types of compounds that are classified as lipids include fatty acids, glycerides, waxes, cholesterol esters, phosphoglycerides and sphingolipids.
