of all living cells. Glycerol esters of fatty acids, which make up to 99% of the lipids of plant and animal origin, have been traditionally called fats and oils. This distinction, based solely on whether the material is solid or liquid at room temperature, is of little practical importance...
A classification of lipids proposed by Bloor contains the following elements, which are useful in distinguishing the many lipid substances: 1.Simple lipids (neutral lipids)-esters of fatty acids with alcohols. a. Fats: esters of fatty acids with glycerol. b. Waxes; esters of fatty acids with ...
Polar lipids were also characterised by higher unsaturation ratios (with the PUFAs content between 60.4 and 66.4%), while saturates (consisted mainly of palmitic and very long-chain saturated fatty acids) were found in higher amounts in sterol esters (ranging between 49.3 and 55.7% of total ...
They are esters of glycerol and fatty acids. Palmitic acid, a saturated fatty acid, is the most widely distributed fatty acid in woody plants, but most fatty acids are unsaturated, oleic and linoleic being most common. Compound lipids, especially phospholipids and glycolipids, are important ...

This reversed ratio has been suggested to be a major cause of the atherogenic effect of cholesterol feeding.'

of the unsaponifiable material present in lipids consists of sterols, with cholesterol being the main sterol component in animal fats and fish oil. Sterols are also found in vegetable oils, but only in trace amounts. Waxes are high-melting point esters of fatty alcohols and fatty acids that ...
8.5 Waxes Waxes are esters of long-chain alcohols with long-chain fatty acids. The resulting molecule can be viewed (in analogy to the glycerolipids) as having a weakly polar head group (the ester moiety itself) and a long, nonpolar tail (the hydrocarbon chains). Fatty acids found in ...
