Fatty Acids: Chemistry, Synthesis and Applications is a comprehensive source of information about a wide range of industrially important fatty acids. This practical resource provides key insights into the chemistry, synthesis, industrial applications, derivatives, and analysis of fatty acids, and the chemical modifications that transform them for use in products from biodiesel fuels to pharmaceuticals.

Written by a team of industry experts, Fatty Acids includes detailed descriptions of fatty acid crystallization, enzymatic synthesis, and microbial production. This book focuses heavily on the chemistry of trans fatty acids, with extensive explanations of their synthesis and measurement. Further, the book addresses advances in the analytical methodology, including mass spectrometry, of fatty acids as well as their derivatives.

This book serves as a reference manual to a new generation of lipid scientists and researchers; a useful resource for oleochemical industries; and a valuable teaching aid for undergraduate and graduate students who are interested in fields related to the chemistry of oils, fats, and food.

• Includes recent developments in the synthesis of fatty acid derivatives, as renewable raw materials for the chemical industry
• Presents efficient synthetic methods for the dietary trans fatty acids in multi-gram scale allowing scientists and researchers to study dietary effects of individual trans fatty acids on human health
• Addresses uses of fats and fatty acids in foods and nutrition
• Identifies the roles of fatty acids and derivatives in cosmetic technology

Abstract

Fatty acids are basic renewable chemical building blocks that can be used as intermediates for a multitude of products. Today the global value of fatty acids exceeds 18 billion dollars and is expected to increase to nearly 26 billion over the period from 2014 to 2019. From its auspicious beginnings, the growth of the fats and oils industry has rested upon the shoulders of those that have gone before and worked tirelessly to understand fatty acids and expand their utilization. Because of the important advances made by these and other researchers, renewable oleochemicals are now an important component of the worldwide chemical industry. This chapter provides a brief general historical perspective of some important developments in the chemistry of fatty acids.

1.1 Introduction

The history of fatty acids is a complex one with discoveries often coinciding. However, a number of landmark developments that had significant impact are covered here. The historian is often challenged by who discovered what and when. Fortunately, most of the major events and discoveries surrounding the chemistry of fatty acids are well documented in journal literature. The application of these discoveries in industry is often times difficult to discern because they are mainly documented in the patent literature, which can be time consuming to search, difficult to interpret, and most patents contain references to other patents, which in turn must be examined for prior art. A chronological summary of important discoveries in fatty acid, oleochemical, and triacylglycerol chemistry is shown in Table 1.1. This list is compiled from various sources including the open literature, patents, and chronological compilations from Blank (1942) and the Cyberlipid website (Anonymous, 2016).
