BMJ, 1962 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. By means of a new

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

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 ...

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

Lipidomics of essential fatty acids and oxygenated metabolites.
Molecular Nutrition & Food Research, 2013Polyunsaturated fatty acids in mammals may be oxygenated into a myriad of bioactive products through di- and monooxygenases, products that are rapidly degraded to control their action.

Clinics in Laboratory Medicine, 1981
Techniques to diagnose developing or frank deficiency of essential fatty acids are explored. EFA deficiency generally is secondary to another disease process or occurs as a side effect of treatment of another disease, such as the long-term administration of fat-free parenteral infusions in patients who cannot eat.

Essential fatty acids are essential to the human body and have benefits for our heart, brain, eyes and joints. By reducing inflammation, blood clots and improving membrane function, essential fats are associated with a lower risk of heart complications –

Essential fatty acids and acne
Journal of the American Academy of Dermatology, 1986Acne is characterized by hyperkeratosis of the follicular epithelium, leading to horny impactions that may lie dormant as open or closed comedones or may cause inflammation of the follicle. Although persons with acne have consistently been observed to have elevated levels of sebum secretion, no mechanism relating sebum secretion rates to comedogenesis ...
