Abstract:
A series of hydroxy fatty acids was identified from a polar glyceride milk-fat fraction. These acids were identified as trimethylsilyl (TMS) ether methyl ester derivatives. Identification was achieved by mass spectral analysis and comparison of gas chromatographic retention times with authentic compounds. Mass spectral fragmentation patterns of the TMS ether methyl esters were obtained, and correlation of important ions for structural identifications were made. In addition, semiquantitative data are presented.

Overview of Fatty Acid Metabolism
Fatty acids are catabolized in a process called beta-oxidation, which takes place in the matrix of the mitochondria and converts their fatty acid chains into two-carbon units of acetyl groups. The acetyl...

Nomenclature of Carboxylic Acid Derivatives: Acid Halides, Esters, and Acid Anhydrides
The IUPAC and common names of acid halides are derived from the corresponding carboxylic acids, by changing “ic acid” to “yl halide.” For example, as shown below, the IUPAC name ethanoyl chloride is derived from ethanoic acid, and the common name, acetyl chloride, is obtained from acetic acid.
