Unsaturated fatty acids [PDF]

open access: yes, 2016
Fatty acids are long-chain hydrocarbons. They are called unsaturated fatty acids when they lack the maximum possible number of hydrogen atoms attached to every carbon atom. For example, if stearic acid, which has 18 carbon atoms and frequently occurs in animal and plant fats, is missing 2 hydrogen atoms, then a double bond is present and the resulting ...

Synthesis of unsaturated fatty acids in the slime mold Physarum polycephalum and the zooflagellates Leishmania tarentolae, Trypanosoma lewisi, and Crithidia sp.: a comparative study

open access: yesJournal of Lipid Research, 1965
On the basis of the unsaturated fatty acids which they synthesize, protists can be grouped in a meaningful way. Thus, the unsaturated fatty acids of the true slime mold are identical with the unsaturated fatty acids of the soil amoebae Acanthamoeba and ...

Unsaturated fatty acids suppress interleukin-2 production and transferrin receptor expression by concanavalin A-stimulated rat Iymphocytes

open access: yesMediators of Inflammation, 1992
The proliferation of T-lymphocytes is dependent upon their ability to synthesize and secrete the cytokine, interleukin-2, and to express cell surface receptors for interleukin-2 and transferrin.

Trans-Fats Inhibit Autophagy Induced by Saturated Fatty Acids

open access: yesEBioMedicine, 2018
Depending on the length of their carbon backbone and their saturation status, natural fatty acids have rather distinct biological effects. Thus, longevity of model organisms is increased by extra supply of the most abundant natural cis-unsaturated fatty ...

Unsaturated fatty acids phosphorylate and destabilize ABCA1 through a protein kinase C δ pathway

open access: yesJournal of Lipid Research, 2007
Abnormal HDL metabolism among patients with diabetes and insulin resistance may contribute to their increased risk of atherosclerosis. ABCA1 mediates the transport of cholesterol and phospholipids from cells to HDL apolipoproteins and thus modulates HDL ...

Residual mitochondrial transmembrane potential decreases unsaturated fatty acid level in sake yeast during alcoholic fermentation [PDF]

open access: yesPeerJ, 2016
Oxygen, a key nutrient in alcoholic fermentation, is rapidly depleted during this process. Several pathways of oxygen utilization have been reported in the yeast Saccharomyces cerevisiae during alcoholic fermentation, namely synthesis of unsaturated ...

Unsaturated Fatty Acids and Pain

open access: yesBiological and Pharmaceutical Bulletin, 2011
Fatty acids, which are the essential nutrients for humans, are an important source of energy and an essential component of cell membranes. They also function as signal transduction molecules in a range of biological phenomena. Recently, an increasing number of physiologic and pharmacologic reports on fatty acids have improved our understanding of the ...

Extraction and diagnosis of fatty acids for Sinorhizobiummeliloti bacteria [PDF]

open access: yesمجلة التربية والعلم, 2014
The current study sought to investigate one of the determining factors of symbiosis between rhizobium bacteria and legumes (i.e. multi sugary acids of Sinorhizobium meliloti), where fatty acids on the lipid A chain were extracted and esterified for ...

Dietary 18-carbon fatty acid unsaturation improves the muscle fiber development and meat quality of Megalobrama amblycephala

open access: yesAquaculture Reports, 2022
The study aimed to investigate the effects of four fatty acids with the same carbon-chain length and different saturations, stearic acid (SA), oleic acid (OA), linoleic acid (LA), and linolenic acid (LNA), on the growth performance and muscle quality of ...
