Nutritional biochemistry of essential fatty acids.

Essential fatty acids: biochemistry, physiology and pathology.

Essential fatty acids (EFAs), linoleic acid (LA), and alpha-linolenic acid (ALA) are essential for humans, and are freely available in the diet. Hence, EFA deficiency is extremely rare in humans. To derive the full benefits of EFAs, they need to be metabolized to their respective long-chain metabolites, i.e., dihomo-gamma-linolenic acid (DGLA), and arachidonic acid (AA) from LA; and eicosapenta...

Consequences of Essential Fatty Acids

Essential fatty acids (EFA) are nutrients that form an amazingly large array of bioactive mediators that act on a large family of selective receptors. Nearly every cell and tissue in the human body expresses at least one of these receptors, allowing EFA-based signaling to influence nearly every aspect of human physiology. In this way, the health consequences of specific gene-environment interac...

Metabolism of Essential Fatty Acids

The fat deficiency disease in the rat (I), dog (2), and chick (3) is characterized in part by sharply increased concentrations of one or more trienoic acids in the tissues, as indicated by alkali isomerization analyses. Indeed, the increase in conjugatable triene in the mitochondrial fatty acids may be the first noticeable symptom of the onset of fat deficiency (4). The major triene component o...

Essential fatty acids extracted from Portulaca oleracea L. leaves

Background & Aim: Purslane (Portulaca oleracea L.), belongs to the Portulacaceace family, grows in many parts of Iran. Results of previous studies were indicated purslane is a rich source of essential fatty acids of omega-3 and omega-6.  Portulaca oleracea is a widespread weed, being the eighth common plants of the world. The Aim of current study was to compare the essential f...
