Polyunsaturated fatty acids as antioxidants

Pharmacological Research, 2008
The susceptibility of fatty acids to oxidation is thought to be directly dependent on their degree of unsaturation. However, some in vitro and in vivo studies suggest that the relation between chemical structure and susceptibility to oxidation is not as straightforward as hypothesized from theoretical viewpoints.

Polyunsaturated Fatty Acids: Biotechnology

Critical Reviews in Biotechnology, 2006
Polyunsaturated fatty acids like EPA and DHA have attracted a great attention due to their beneficial effects on human health. At present, fish oil is the major source of EPA and DHA. Various alternative sources are being explored to get these essential fatty acids.

Polyunsaturated fatty acids of the retina

Progress in Lipid Research, 1981
Polyunsaturated acyl chains provide the lipid matrix of membranes with a high degree of fluidity, facilitating translational, rotational and vibrational forms of motion to protein constituents. One of the most highly fluid membranes found in nature is that from the outer segments of photoreceptors, within which movements of rhodopsin have been measured,

Polyunsaturated Fatty Acids and Ethanol

Advances in Alcohol & Substance Abuse, 1988
Ethanol exposure leads to a loss in membrane polyunsaturated fatty acids (PUFA). It is proposed that polyunsaturated species of phospholipids are not randomly distributed, but are concentrated in the cytosolic leaflets of the plasma membrane and are preferentially associated with membrane proteins. These lipids affect the physical state of environments

Polyunsaturated fatty acids and inflammation

IUBMB Life, 2015
AbstractInflammation is a protective process for life that aims to restore body homeostasis by targeting the injury and by inducing repair mechanisms. This process can also become excessive and lead to chronic inflammation and organ fibrosis. Polyunsaturated fatty acids play a key role in inflammatory processes and their resolution.

Polyunsaturated Fatty Acids

Journal of Gerontological Nursing, 2011
The immune system tends to become less efficient as people age, and nutrition plays a significant role in older adults’ immune responses. In particular, dietary fatty acids are precursors to important immune system components. Certain fatty acids, predominantly those that are polyunsaturated, also tend to decrease the risk of certain neurological ...

Enzymatic Purification of Polyunsaturated Fatty Acids.

Journal of Bioscience and Bioengineering, 2001
Polyunsaturated fatty acids (PUFAs) have various physiological functions. Of these, ethyl eicosapentaenoate is industrially purified and used as a medicine. Other PUFAs, such as docosahexaenoic acid (DHA), gamma-linolenic acid (GLA), and arachidonic acid (AA), are also expected to be used as pharmaceutical agents; however, their industrial purification

The Polyunsaturated Fatty Acids of Microorganisms

1966
Publisher Summary This chapter discusses the polyunsaturated fatty acids of microorganisms. Polyunsaturated or polyenoic fatty acids are those long-chain fatty acids that include two or more double bonds in the molecule. It is widely accepted that bacteria are incapable of synthesizing polyenoic fatty acids, and this generalization applies equally to

Plasmalogens and Polyunsaturated Fatty Acids

2008
The analysis of polyunsaturated fatty acids (“essential fatty acids”) in plasma and erythrocytes is carried out by gas chromatography of their methyl esters following trans-methylation of the fatty acid esters. The O-alkenyl ethers or plasmalogens – an important group of phospholipids – are converted into dimethylacetals in this process and can be ...

Polyunsaturated fatty acids in infant nutrition

Acta Paediatrica, 1994
The availability of long‐chain polyunsaturated fatty acids (LCP), such as arachidonic (C20:4n‐6) and docosahexaenoic (C22:6n‐3) acids, is important for early human growth and development. The capacity for endogenous synthesis of LCP from the precursor fatty acids lineoleic (C18:2n‐6) and alpha‐linolenic (C18:3n‐3) acid is limited in preterm and ...
