PREVIOUS work1 on the relationship between chemical structure and biological activity of fatty acids was based on the theory that either the 6-term. (that is, a double bond between the 6th and 7th carbon-atom counted from the terminal methyl group) or the 9-term. double bonds or both were fundamental for essential fatty acid activity.

Publisher Summary This chapter explains structural requirements, metabolism of action, and the role of the essential fatty acids. These acids are metabolized in ways common to other unsaturated fatty acids. In addition, the unsaturated acids possessing the 9, 12 double bond system (C18 acids) or the 11–14 double bond system (C20 acids) possesses ...

Nutrition in Clinical Practice, 1992
In animal and human tissues, there are four families of fatty acids that are derived from the precursors palmitoleic, oleic, linoleic, and linolenic acids. Of these, linoleic and linolenic acids are essential dietary elements for humans and all higher animals. The four precursor fatty acids are metabolized (through desaturation and chain elongation) to

Lipids, 1999
AbstractAll fatty acids have important functions, but the term “essential” is applied only to those polyunsaturated fatty acids (PUFA) that are necessary for good health and cannot be completely synthesized in the body. The need for arachidonic acid, which is utilized for eicosanoid synthesis and is a constituent of membrane phospholipids involved in ...

Essential Fatty Acids Revisited
Archives of Pediatrics & Adolescent Medicine, 1980Polyunsaturated fatty acids (PUFAs) are aliphatic monocarboxylic acids with two or more double bonds in any positional arrangement or geometric configuration. Those PUFAs that prevent or relieve the symptoms of dietary deficiency in humans and animals are named, therefore, the essential fatty acids (EFAs).

The Essentials of Essential Fatty Acids
Journal of Dietary Supplements, 2009All fats, including saturated fatty acids, have important roles in the body. However, the most important fats are those that the body cannot make and thus must come from the food we eat. These essential fatty acids (EFAs) are based on linoleic acid (omega-6 group) and alpha-linolenic acid (omega-3 group). We need both groups of essential fatty acids to

Linoleic acid, gamma-linoleic acid and arachidonic acid are essential substrates for human nutrition. The daily requirement of linoleic acid or linoleic acid equivalent are 6.5 g/die. The recommended dietary allowance (RDA) for safety intake has been fixed to 10 g/die.

ESSENTIAL FATTY ACIDS AND PROSTAGLANDINS
1974Arachidonic acid takes part in a number of complicated enzymic processes in which not only the prostaglandins but also the intermediate products of their biosynthesis have important physiological effects. The prostaglandin-synthesizing system can convert a large number of nonnatural substrates, leading to the formation of substituted prostaglandins ...

Essential Fatty Acid Requirements and Intravenous Lipid Emulsions.
JPEN - Journal of Parenteral and Enteral Nutrition, 2019Linoleic acid (LA) and α-linolenic acid (ALA) must be supplied to the human body and are therefore considered essential fatty acids. This narrative review discusses the signs, symptoms, diagnosis, prevention, and treatment of essential fatty acid ...
