Lipid Essentials

Structures, Occurrence, Basic Biochemistry and Function

Lipids are a diverse range of compounds for which no internationally agreed definition exists. In our articles A Lipid Primer and on nomenclature, we define lipids as fatty acids and their derivatives, and substances related biosynthetically or functionally to these compounds. A general summary of the structures, occurrence, composition, chemical and physical properties, basic biochemistry and function of these vital and fascinating natural compounds is presented here. In particular, the first two articles listed below describe in general terms what lipids are and why they are so important in nature.

cartoonFurther documents in the 'Lipid Essentials' topic of this website are grouped into four main sections according to chemical structures, and they can be addressed from the following links -

Related lipids are grouped together as far as possible in these web pages, but there are some that do not fit easily into any group and most of these are listed with the simple lipids for reasons of practical convenience.

These essays are aimed at generalists - not experts in particular disciplines - but the reading lists at the end of each provide for those who require a more specialized knowledge. In addition, the Literature Survey pages contain comprehensive lists of those publications consulted during the writing of this section of the site. As I am able to update them regularly, my web pages here are much more up-to-date and accurate, and they are far better illustrated than obsolete versions elsewhere.

I can recommend the following websites that provide complementary information to this - - lipid structures and composition; Lipid Maps - lipid systematics and structures; PhyloFAdb - phylogenetic relationships between fatty acids and plants.
