Chemistry of fatty acids

The chemistry of fatty acid methyl ester (FAME) sulfonation is complicated and not yet fully elucidated, but it may be summarized as depicted in the following reaction scheme. The initial reaction between FAME and S03, although fast, is far from instantaneous. Two intermediate products are formed ...

On first examination, fatty acid synthesis appears to be simply the reverse of (3-oxidation. Specifically, the fatty acid chain is constructed by the sequential addition of two-carbon acetyl groups (Figure 23.11). Although the chemistry of fatty acid synthesis and breakdown are similar, there are several major differences between (3-oxidation and fatty acid biosynthesis. These are summarized as follows. 

Marine fatty acids continue to occupy a central role in modem marine natural products research because of the unusual array of structural motifs constantly being discovered. Most novel fatty acids were identified in marine invertebrates or marine microorganisms. Although excellent reviews of the syntheses of terrestrial fatty acids are published frequently and several outstanding reviews about the chemistry of fatty acids have appeared recently [1], there has been no review of the synthetic methodology used in the preparation of marine fatty acids. Therefore, this review presents a compilation of what has been published recently regarding the synthesis of unusual marine fatty acids, some of... 

Prior to discussing the chemical structures and properties of the saponifiable lipids, it is useful to first describe the chemistry of fatty acids, the fundamental building blocks of many lipids. Fatty acids (defined in Section 5.1) are long-chain carboxylic acids, as shown in I Figure 8.4. It is the long nonpolar tails of fatty acids that are responsible for... 

The chemistry of fatty acids is far more complex than might be imagined from this brief description, with features such as micellisation in aqueous solution and dimerisation in organic solvent being important factors likely to affect coating behaviour. Unfortunately these aspects have largely been overlooked in this context. For a... 

The finding that carboxyl groups of fatty acids tend to remain carboxyl groups in acetoacetate and that methyl groups tend to remain methyl groups supported speculation that two types of active acetate were formed, with different propensities for reaction, but both capable of entering either end of acetoacetate. More recent studies on the chemistry of fatty acid oxidation have found evidence for only one 2-carbon...
