Detect the small but subtle differences of fatty acid isomers!

Introduction

Fatty acids have a well documented effect on health. On one hand unsaturated fatty acids are essential especially the omega-3 fatty acids which are beneficial in preventing heart diseases. The carbon-carbon double bonds of these essential fatty acids are cis type. On the other hand, fatty acids containing trans type double bonds are harmful to health. They are known to increase the risk of coronary heart diseases. During the industrial processing of foodstuffs such as margarine cis fatty acids are used.

Therefore, it is essential to monitor the types of fatty acids in food. The position as well as the nature of the double bonds needs to be determined.
