Evaluation of four derivatization methods for the analysis of fatty acids from green leafy vegetables by gas chromatography.

J. Chromatogr. B. Analyt. Technol. Biomed. Life Sci. 990 , 150-7, (2015)

Green leafy vegetables are valuable secondary sources of nutrients, including lipids, commonly consumed in developing countries. However, method development for the analysis of fatty acids is usually focused on the animal lipid samples, rarely including natur...

The role of 18-methyleicosanoic acid in the structure and formation of mammalian hair fibres.

Micron 28 , 469-485, (1997)

Although branched chain fatty acids perform many functions in biological systems, the importance of the anteiso 18 methyleicosanoic acid (MEA) has only recently been recognized. In this first review on MEA its role and distribution is explored. MEA has been f...

Effect of the covalently linked fatty acid 18-MEA on the nanotribology of hair's outermost surface.

J. Struct. Biol. 149 , 235-242, (2005)

Highly ordered lipids adsorbed or grafted on surfaces are known to provide protection and lubrication custom engineered surfaces. We have used atomic force microscopy (AFM) to measure adhesion and frictional properties of the outermost surfaces of a variety o...

A role of the anteiso branch of 18-MEA in 18-MEA/SPDA to form a persistent hydrophobicity to alkaline-color-treated weathered hair.

J. Cosmet. Sci. 60 , 509-518, (2009)

The effect of the anteiso-branch moiety of 18-MEA (18-methyleicosanic acid) to create a persistent hydrophobicity of alkaline-color-treated weathered hair treated with 18-MEA/SPDA (stearoxypropyldimethylamine) was investigated by comparing a straight-chain fa...

Maple syrup urine disease hair reveals the importance of 18-methyleicosanoic acid in cuticular delamination.

Micron 36 , 261-266, (2005)

18-Methyleicosanoic acid (18-MEA) is thought to be covalently bound to the outer surface of human hair and is a major component of the outer beta-layer of the cuticular cell membrane complex (CCMC). Cuticular delamination, whether this occurs between the oute...
