Overview of Lipids, Fatty Acids, and Eicosanoids

Derived lipids are obtained by hydrolysis of simple and compound lipids, including fatty acids, glycerol, alcohols, steroids, carotenoids, ketone bodies, and fat-soluble vitamins.
Free fatty acids are monocarboxylic acids with chain lengths ranging from 2 to about 34 carbon atoms, usually found as esters in lipids.
Saturated fatty acids have an even number of carbon atoms and may be saturated or unsaturated, while unsaturated fatty acids are either monounsaturated or polyunsaturated.
Nonessential fatty acids can be synthesized in the body, while essential fatty acids cannot be synthesized at a sufficient rate and must be obtained from the diet.
Essential fatty acids include linoleic acid, linolenic acid, arachidonic acid, and clupanodonic acid, and are required for membrane structure and function, transport of cholesterol, formation of lipoproteins, prevention of fatty liver, and synthesis of eicosanoids.
Carbon atoms in fatty acids can be numbered from the carboxylic group, the carbon adjacent to the carboxyl carbon, or the last methylcarbon (omega carbon).
Physical properties of fatty acids vary depending on chain length and saturation, with volatile and soluble fatty acids found in milk fat and solid and insoluble fatty acids found in longer chain saturated fatty acids.
Chemical properties of fatty acids involve reactions with the carboxyl group, including esterification and saponification, as well as reactions with the hydrocarbon chain, including hydrogenation, halogenation, and oxidation.
Unsaturated fatty acids are more reactive than saturated fatty acids due to the presence of double bonds, and can form peroxide derivatives, ketones, aldehydes, and acids with smaller carbon chains.
Prostaglandins and eicosanoids are cyclic compounds derived from arachidonic acid through cyclization of its carbon chain to form a ring, and are important for inflammation and pain regulation.
Glycerol is a polyhydric alcohol containing 3 hydroxyl groups, and is colorless.
Lipids, fatty acids, and eicosanoids have important roles in the body, including energy storage, insulation, membrane structure and function, and regulation of inflammation and pain.
