All 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 signal transduction, is the main reason why the n-6 class of PUFA are essential. Physiological data indicate that n-3 PUFA also are essential. Although… 
Plasma free fatty acid and lipoproteins as sources of polyunsaturated fatty acid for the brain
TLDR
It is suggested that the brain probably can obtain an adequate supply of n-6 PUFA from either the plasma FFA or lipoproteins, and if the brain requires large amounts of preformed DHA, the phospholipids contained in plasma lipoproteinins are the most likely source.

Discovery of essential fatty acids
TLDR
The discovery of essential fatty acids was a paradigm-changing finding, and it is now considered to be one of the landmark discoveries in lipid research.
Emergence of omega-3 fatty acids in biomedical research.
Docosahexaenoic acid (DHA): An essential nutrient and a nutraceutical for brain health and diseases.
Docosahexaenoic Acid (DHA) and Hepatic Gene Transcription, 1,3
TLDR
This analysis will reveal that changes in hepatic 22:6,n-3 content has a major impact on hepatic lipid and carbohydrate metabolism and suggest that either novel or atypical PKCs are involved in the of both Gsk-3 β phosphorylation and SREBP-1 nuclear abundance.
n-3 PUFA Sources (Precursor/Products): A Review of Current Knowledge on Rabbit
TLDR
Sustainable sources of n-3 PUFAs are limited and exert a different effect about the form in which they are administered, precursor or derivatives; (2) their antioxidant protections; and (3) the purpose to be achieved.

N-3 fatty acid deficiency in the rat pineal gland: effects on phospholipid molecular species composition and endogenous levels of melatonin and lipoxygenase products.
TLDR
Investigating the effect of n-3 essential fatty acid status on two key pineal biochemical functions, melatonin production and lipoxygenation, using pineal glands from rats given an n-1-adequate or n-2-deficient diet suggests that n- 3 fatty acids may play a critical role in regulating pineal function.
Conversion of eicosapentaenoic acid to chain-shortened omega-3 fatty acid metabolites by peroxisomal oxidation.
TLDR
It is demonstrated that as in the case of arachidonic acid, chain-shortened polyunsaturated fatty acid products accumulate when EPA undergoes peroxisomal beta-oxidation.
Depletion of arachidomic acid from GH3 cells
TLDR
The results show that arachidonic acid itself is not required for operation of the phosphatidylinositol cycle and is not an obligatory intermediate in TRH-mediated GH3 cell activation and transient events such as stimulated breakdown of inositol phospholipids and an initial rise in diacylglycerol are enhanced by the presence of arachidonate.
Depletion of arachidonic acid from GH3 cells. Effects on inositol phospholipid turnover and cellular activation.
TLDR
The results show that arachidonic acid itself is not required for operation of the phosphatidylinositol cycle and is not an obligatory intermediate in TRH-mediated GH3 cell activation and transient events such as stimulated breakdown of inositol phospholipids and an initial rise in diacylglycerol are enhanced by the presence of arachidonate.
Effects of omega-3 fatty acids on vascular smooth muscle cells: Reduction in arachidonic acid incorporation into inositol phospholipids
TLDR
It is suggested that when omega-3 fatty acids are available, less arachidonic acid is channeled into the inositol phospholipids of activated smooth muscle cells because of replacement by EPA.
Astrocytes, Not Neurons, Produce Docosahexaenoic Acid (22:6ω‐3) and Arachidonic Acid (20:4ω‐6)
TLDR
It is suggested that astrocytes play an important supportive role in the brain by elongating and desaturating ω‐6 and ω-3 essential fatty acid precursors to 20:4ω‐6and 22:6ω‐3, then releasing the long‐chain polyunsaturated fatty acids for uptake by neurons.

TLDR
It is demonstrated that only certain transport systems are sensitive to the polyunsaturated fatty acid content of the retinoblastoma cell membrane.
A role for phospholipid polyunsaturation in modulating membrane protein function
TLDR
The relationship amongsn-2 acyl chain unsaturation, cholesterol content, and MII formation is explained on the basis of variation in fv with bilayer lipid composition and a novel model for the packing of phospholipids containing polyenoic acyl chains, such as 22:6n-3.
Choline Uptake in Cultured Human Y79 Retinoblastoma Cells: Effect of Polyunsaturated Fatty Acid Compositional Modifications
TLDR
The results suggest that one functional effect of the high unsaturated fatty acid content of neural cell membranes is to facilitate the capacity of thehigh‐affinity choline uptake system to transport low concentrations of choline.
