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

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 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 ...

Essential fatty acids and the skin
British Journal of Dermatology, 1989The realisation that essential fatty acids are of crucial importance for the maintenance of a healthy skin coincided with their discovery. Burr and Burr (1) first described the symptoms of essential fatty acid deficiency thus: “An abnormal, scaly condition of the skin is observed between the 70th and 90th day of life.

Essential fatty acids and their derivatives
Current Opinion in Gastroenterology, 2005This review will address recent research in metabolism of essential fatty acids and their long chain derivatives. Our main focus will be the association between essential fatty acid status and various disease states, as well as the effects of supplementation with essential fatty acids or their derivatives on a number of clinical outcomes.There have ...

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 ...

Nutrition & Food Science, 1972
Essential fatty acids are substances that an animal organism — which includes that of humans — needs for certain physiological and metabolic processes. This is almost a definition of vitamins, and they were indeed known as vitamin F in the early days, but the daily requirement of them is so much greater than that of vitamins that the name has lapsed ...
