The isolation and partial characterization of the serum lipoproteins and apolipoproteins of the rainbow trout. (1/15636)1. VLD (very-low-density), LD (low-density) and HD (high-density) lipoproteins were isolated from the serum of trout (Salmo gairdneri Richardson). 2. Each lipoprotein class resembled that of the human in immunological reactivity, electrophoretic behaviour and appearance in the electron microscope. Trout LD lipoprotein, however, was of greater density than human LD lipoprotein. 3. The trout lipoproteins have lipid compositions which are similar to those of the corresponding human components, except for their high contents of long-chain unsaturated fatty acids. 4. HD and LD lipoproteins were immunologically non-identical, whereas LD lipoproteins possessed antigenic determinants in common with VLD lipoproteins. 5. VLD and HD lipoproteins each contained at least seven different apoproteins, whereas LD liprotein was composed largely of a single apoprotein which resembled human apolipoprotein B. 6. At least one, and possibly three, apoprotein of trout HD lipoprotein showed features which resemble human apoprotein A-1.7. The broad similarity between the trout and human lipoprotein systems suggests that both arose from common ancestral genes early in evolutionary history. (+info)
Fish oil feeding delays influenza virus clearance and impairs production of interferon-gamma and virus-specific immunoglobulin A in the lungs of mice. (2/15636)Ingestion of fish oil can suppress the inflammatory response to injury and may impair host resistance to infection. To investigate the effect of a diet containing fish oil on immunity to viral infection, 148 BALB/c mice were fed diets containing 3 g/100 g of sunflower oil with either 17 g/100 g of fish oil or beef tallow for 14 d before intranasal challenge with live influenza virus. At d 1 and d 5 after infection, the mice fed fish oil had higher lung viral load and lower body weight (P < 0.05). In addition to the greater viral load and weight loss at d 5 after infection, the fish oil group consumed less food (P < 0.05) while the beef tallow group was clearing the virus, had regained their preinfection weights and was returning to their preinfection food consumption. The fish oil group had impaired production of lung interferon-gamma (IFN-gamma), serum immunoglobulin (Ig) G and lung IgA-specific antibodies (all P < 0. 05) although lung IFN-alpha/beta and the relative proportions of bronchial lymph node CD4+ and CD8+ T lymphocytes did not differ between groups after infection. The present study demonstrates a delay in virus clearance in mice fed fish oil associated with reduced IFN-gamma and antibody production and a greater weight loss and suppression of appetite following influenza virus infection. However, differences observed during the course of infection did not affect the ultimate outcome as both groups cleared the virus and returned to preinfection food consumption and body weight by d 7.

Enhanced myocardial glucose use in patients with a deficiency in long-chain fatty acid transport (CD36 deficiency). (3/15636)CD36 is a multifunctional, 88 kDa glycoprotein that is expressed on platelets and monocytes/macrophages. CD36 also has high homology with the long-chain fatty acid (LFA) transporter in the myocardium. Although platelet and monocyte CD36 levels can indicate a CD36 deficiency, they cannot predict specific clinical manifestations in the myocardium of a given person. We examined the hypothesis that a deficiency in LFA transport augments myocardial glucose uptake in patients with a type I CD36 deficiency. METHODS: Seven fasting patients with a type I CD36 deficiency and 9 controls were assessed by cardiac radionuclide imaging using beta-methyl-p-iodophenyl-pentadecanoic acid (BMIPP) as a LFA tracer and by PET with 18F-fluorodeoxyglucose (FDG). RESULTS: None of the patients with a CD36 deficiency showed myocardial uptake of BMIPP. The percentage dose uptake of BMIPP in these subjects was significantly lower than that in normal controls (1.31+/-0.24 versus 2.90+/-0.2; P < 0.005). PET studies revealed that myocardial FDG accumulation was substantially increased in patients with a CD36 deficiency. Quantitative analysis showed that the percentage dose uptake of FDG in patients with a CD36 deficiency was significantly higher than that in normal controls (1.28+/-0.35 versus 0.43+/-0.22; P< 0.01). CONCLUSION: CD36 functions as a major myocardial LFA transporter and its absence may cause a compensatory upregulation of myocardial glucose uptake. (+info)
S-myristoylation of a glycosylphosphatidylinositol-specific phospholipase C in Trypanosoma brucei. (4/15636)Covalent modification with lipid can target cytosolic proteins to biological membranes. With intrinsic membrane proteins, the role of acylation can be elusive. Herein, we describe covalent lipid modification of an integral membrane glycosylphosphatidylinositol-specific phospholipase C (GPI-PLC) from the kinetoplastid Trypanosoma brucei. Myristic acid was detected on cysteine residue(s) (i.e. thiomyristoylation). Thiomyristoylation occurred both co- and post-translationally. Acylated GPI-PLC was active against variant surface glycoprotein (VSG). The half-life of fatty acid on GPI-PLC was 45 min, signifying the dynamic nature of the modification. Deacylation in vitro decreased activity of GPI-PLC 18-30-fold. Thioacylation, from kinetic analysis, activated GPI-PLC by accelerating the conversion of a GPI-PLC.VSG complex to product. Reversible thioacylation is a novel mechanism for regulating the activity of a phospholipase C. (+info)
Separation of molecular species of glucosylceramide by high performance liquid chromatography of their benzoyl derivatives. (5/15636)The method of separation of glucosylceramide by HPLC was reported. Glucosylceramide was perbenzoylated and separated on a packed muBondapack C18 column, using methanol as eluting solvent. The pattern obtained by HPLC closely resembled that obtained by GLC of the TMS-glucosylceramide, and reflected the molecular species of fatty acid components. This method is reproducible, and sensitive as GLC. This method also can be used for analysis of higher glycolipids. (+info)
Gangliosides of human kidney. (6/15636)Five gangliosides isolated from human kidney have been characterized. The two main fractions were shown to be typical extraneural gangliosides in having lactose as their neutral carbohydrate moiety. Their structures were identified as: AcNeu(alpha2-3)Gal(beta1-4)Glc(beta1-1)Cer and AcNeu(alpha2-8)AcNeu(alpha2-3)Gal(beta1-4)Glc(beta1-1)Cer. The two main hexosamine-containing gangliosides are structurally related to human blood group substances of glycosphingolipid nature. The following structures are postulated: AcNeu(alpha2-3)Gal(beta1-4)GlcNAc(beta1-3)Gal(beta1-4)Glc(beta1-1)Cer and AcNeu(alpha2-3)Gal(beta1-4)[Fuc(alpha1-3)]GlcNAc(beta1-3)Gal(beta1-4)Glc(beta1-1) Cer. The third hexosamine-containing ganglioside belongs to a different series of glycolipids and was shown to have the structure of a major ganglioside of human brain: AcNeu(alpha2-3)Gal(beta1-3)GalNAc(beta1-4)[AcNeu(alpha2-3)]Gal(beta1-4)Glc(beta1- 1)Cer. The fatty acid structure of different gangliosides was shown to resemble that of neutral glycolipids of human kidney with the nonhydroxy acids C16:0, C22:0, and C24:0 as major components. (+info)
Desulfocella halophila gen. nov., sp. nov., a halophilic, fatty-acid-oxidizing, sulfate-reducing bacterium isolated from sediments of the Great Salt Lake. (7/15636)A new halophilic sulfate-reducing bacterium, strain GSL-But2T, was isolated from surface sediment of the Southern arm of the Great Salt Lake, UT, USA. The organism grew with a number of straight-chain fatty acids (C4-C16), 2-methylbutyrate, L-alanine and pyruvate as electron donors. Butyrate was oxidized incompletely to acetate. Sulfate, but not sulfite or thiosulfate, served as an electron acceptor. Growth was observed between 2 and 19% (w/v) NaCl with an optimum at 4-5% (w/v) NaCl. The optimal temperature and pH for growth were around 34 degrees C and pH 6.5-7.3, respectively. The generation time under optimal conditions in defined medium was around 28 h, compared to 20 h in complex medium containing yeast extract. The G+C content was 35.0 mol%. 16S rRNA gene sequence analysis revealed that strain GSL-But2T belongs to the family Desulfobacteriaceae within the delta-subclass of the Proteobacteria and suggested that strain GSL-But2T represents a member of a new genus. The name Desulfocella halophila gen. nov., sp. nov. is proposed for this organism. The type strain of D. halophila is strain GSL-But2T (= DSM 11763T = ATCC 700426T). (+info)
Actinobacillus succinogenes sp. nov., a novel succinic-acid-producing strain from the bovine rumen. (8/15636)Strain 130ZT was isolated from the bovine rumen. It is a facultatively anaerobic, pleomorphic, Gram-negative rod. It exhibits a 'Morse code' form of morphology, which is characteristic of the genus Actinobacillus. Strain 130ZT is a capnophilic, osmotolerant succinogen that utilizes a broad range of sugars. It accumulates high concentrations of succinic acid (> 70 g l-1). Strain 130ZT is positive for catalase, oxidase, alkaline phosphatase and beta-galactosidase, but does not produce indole or urease. Acid but no gas is produced from D-glucose and D-fructose. 16S rRNA sequence analysis places strain 130ZT within the family Pasteurellaceae; the most closely related members of the family Pasteurellaceae have 16S rRNA similarities of 95.5% or less with strain 130ZT. Strain 130ZT was compared with Actinobacillus lignieresii and the related Bisgaard Taxa 6 and 10. Based upon morphological and biochemical properties, strain 130ZT is most similar to members of the genus Actinobacillus within the family Pasteurellaceae. It is proposed that strain 130ZT be classified as a new species, Actinobacillus succinogenes. The type strain of Actinobacillus succinogenes sp. nov. is ATCC 55618T. (+info)
Author Summary Vaccinia virus, the prototypic poxvirus, is closely related to variola virus, the etiological agent of smallpox. A full understanding of the poxviral life cycle is imperative for the development of novel antiviral therapies, the design of new vaccines, and the effective and safe use of these viruses as oncolytic agents. Metabolomic studies have shed light on the novel mechanisms used by viruses to replicate efficiently within their hosts. de novo fatty acid biosynthesis has been shown to be of relevance for numerous viral infections as well as for the development of cancer. Here we describe an important role for de novo fatty acid biosynthesis during vaccinia infection. Ongoing synthesis of palmitate is needed to fuel the production of energy within mitochondria. The biochemical events of viral DNA replication and protein synthesis are minimally affected by inhibition of this pathway, but viral assembly is disrupted more dramatically. Further exploration of this pathway will provide

The fatty acid compositions of the neutral lipid and phospholipid fractions of rat lymph node lymphocytes were characterized. Stimulation of rat lymphocytes with the T-cell mitogen concanavalin A resulted in significant changes in the fatty acid composition of both neutral lipids and phospholipids (a decrease in the proportions of stearic, linoleic and arachidonic acids and an increase in the proportion of oleic acid). Membrane fluidity was measured using nitroxide spin-label e.s.r., and increased during culture with concanavalin A. Culturing the lymphocytes in the absence of mitogen did not affect fatty acid composition or membrane fluidity. The uptake and fate of palmitic, oleic, linoleic and arachidonic acids were studied in detail; there was a time-dependent incorporation of each fatty acid into all lipid classes but each fatty acid had a characteristic fate. Palmitic and arachidonic acids were incorporated principally into phospholipids whereas oleic and linoleic acids were incorporated in similar
Background Combinations of multiple fatty acids may influence cardiometabolic risk more than single fatty acids. The association of a combination of fatty acids with incident type 2 diabetes (T2D) has not been evaluated. Methods and findings We measured plasma phospholipid fatty acids by gas chromatography in 27,296 adults, including 12,132 incident cases of T2D, over the follow-up period between baseline (1991-1998) and 31 December 2007 in 8 European countries in EPIC-InterAct, a nested case-cohort study. The first principal component derived by principal component analysis of 27 individual fatty acids (mole percentage) was the main exposure (subsequently called the fatty acid pattern score [FA-pattern score]). The FA-pattern score was partly characterised by high concentrations of linoleic acid, stearic acid, odd-chain fatty acids, and very-long-chain saturated fatty acids and low concentrations of γ-linolenic acid, palmitic acid, and long-chain monounsaturated fatty acids, and it explained ...
Extracellular fatty acid incorporation into the phospholipids of Staphylococcus aureus occurs via fatty acid phosphorylation. We show that fatty acid kinase (Fak) is composed of two dissociable protein subunits encoded by separate genes. FakA provides the ATP binding domain and interacts with two distinct FakB proteins to produce acyl-phosphate. The FakBs are fatty acid binding proteins that exchange bound fatty acid/acyl-phosphate with fatty acid/acyl-phosphate presented in detergent micelles or liposomes. The ΔfakA and ΔfakB1 ΔfakB2 strains were unable to incorporate extracellular fatty acids into phospholipid. FakB1 selectively bound saturated fatty acids whereas FakB2 preferred unsaturated fatty acids. Affymetrix array showed a global perturbation in the expression of virulence genes in the ΔfakA strain. The severe deficiency in α-hemolysin protein secretion in ΔfakA and ΔfakB1 ΔfakB2 mutants coupled with quantitative mRNA measurements showed that fatty acid kinase activity was ...
This paper describes the fuel properties, combustion characteristics and exhaust emissions of the methyl esters of saturated fatty acid with 6 to 10 carbons in the molecule chain. The fuels blend (50/50 mass%) of three saturated fatty acid methyl esters (methyl caproate, methyl caprylate, methyl caprate); with methyl laurate as a base fuel are tested using a DI diesel engine. From the experimental results, the blend of saturated fatty acid methyl ester with a lower carbon number has a lower kinematic viscosity, pour point and smoke emission, though having longer ignition delay, the same as long chain saturated fatty acid methyl ester ...
Nowadays the industrial chemistry reactions rely on green technologies. Enzymes as lipases are increasing its use in diverse chemical processes. Epoxidized fatty acid methyl esters obtained from transesterification of vegetable oils have recently found applications as polymer plasticizer, agrochemical, cosmetics, pharmaceuticals and food additives. In this research article, grapeseed, avocado and olive oils naturally containing high percents of mono and poly unsaturations were used as starting materials for the production of unsaturated fatty acid methyl esters. The effect of lauric acid as an active oxygen carrier was studied on epoxidation reactions where unsaturated fatty acid methyl esters were converted to epoxy fatty acid methyl esters using immobilized Candida antarctica Lipase type B as catalyst and hydrogen peroxide as oxygen donor at mild temperature and pressure conditions. After this study it was confirmed by 1H NMR, 13C NMR and GC-MS that the addition of lauric acid to the enzymatic

Fatty acids of platelet phospholipid fractions, platelet aggregation, and thromboxane B2 (TXB2) formation were analyzed at 0, 2, and 4 months of treatment and at 1, 2, and 3 months of wash-out. During n-3 PUFA supplementation, accumulations of eicosapentaenoic (EPA), docosapentaenoic (DPA), and docosahexaenoic (DHA) acids were markedly increased after 2 months, with slight differences in further accumulation up ...
TY - JOUR. T1 - Imaging of myocardial fatty acid oxidation. AU - Mather, Kieren J.. AU - DeGrado, Timothy R. PY - 2016/1/21. Y1 - 2016/1/21. N2 - Myocardial fuel selection is a key feature of the health and function of the heart, with clear links between myocardial function and fuel selection and important impacts of fuel selection on ischemia tolerance. Radiopharmaceuticals provide uniquely valuable tools for in vivo, non-invasive assessment of these aspects of cardiac function and metabolism. Here we review the landscape of imaging probes developed to provide non-invasive assessment of myocardial fatty acid oxidation (MFAO). Also, we review the state of current knowledge that myocardial fatty acid imaging has helped establish of static and dynamic fuel selection that characterizes cardiac and cardiometabolic disease and the interplay between fuel selection and various aspects of cardiac function.This article is part of a Special Issue entitled: Heart Lipid Metabolism edited by G.D. ...
The heart relies predominantly on a balance between fatty acids and glucose to generate its energy supply. There is an important interaction between the metabolic pathways of these two substrates in the heart. When circulating levels of fatty acids are high, fatty acid oxidation can dominate over glucose oxidation as a source of energy through feedback inhibition of the glucose oxidation pathway. Following an ischaemic episode, fatty acid oxidation rates increase further, resulting in an uncoupling between glycolysis and glucose oxidation. This uncoupling results in an increased proton production, which worsens ischaemic damage. Since high rates of fatty acid oxidation can contribute to ischaemic damage by inhibiting glucose oxidation, it is important to maintain proper control of fatty acid oxidation both during and following ischaemia. An important molecule that controls myocardial fatty acid oxidation is malonyl-CoA, which inhibits uptake of fatty acids into the mitochondria. The levels of ...
This paper aims to report the authors study of the fatty acid methyl ester consisting of plant oil or animal fat in hope to improve the effectiveness and profitability of its practical application.As is known,the fatty acid methyl ester is a kind of bio-diesel that is likely to be used as fuel of diesel engine with the environment-friendly properties.The present paper has compared the properties of fatty acid methyl ester and diesel oil by conducting experiments on a four-cylinder turbo-charge direct injection diesel engine at a compression ratio of 18 and rated power of 76 kW at 3 800 r/min.When the engine is fueled with diesel oil,fatty acid methyl ester,the blended fuel consisting of fatty acid methyl ester and diesel at a ratio of 30% to 70% and 50% to 50% in weight under two working conditions.That is to say,let the engine work at its full load at the speed of 1 800 r/min and 2 200 r/min,and watch how about the engine performs its duty.While testing such behaviors as power,energy consumption
Resistance to the action of insulin affects fatty acid delivery to the liver, fatty acid synthesis and oxidation within the liver, and triglyceride export from the liver. To understand the metabolic consequences of hepatic fatty acid synthesis, partitioning, oxidation, and net liver fat content in the fasted and postprandial states, we used stable-isotope tracer methodologies to study healthy men and women with varying degrees of insulin resistance before and after consumption of a mixed meal. Subjects were classified as being normoinsulinemic (NI) (fasting plasma insulin |11.2 mU/L, n = 18) or hyperinsulinemic (HI) (fasting plasma insulin |11.2 mU/L, n = 19). Liver fat content was similar between HI and NI individuals, despite HI subjects having marginally more visceral fat. However, de novo lipogenesis was higher and fatty acid oxidation was lower in HI individuals compared with NI subjects. These data suggest that metabolic pathways promoting fat accumulation are enhanced in HI but, paradoxically,
The present study quantifies the relationships between diet fatty acid profile and fatty acid composition of rat skeletal muscle phospholipids. Young adult male Sprague-Dawley rats were fed, for 8 weeks, on one of twelve moderate-fat diets (25% of total energy) differing only in fatty acid profile. SFA content ranged from 8-88% of total fatty acids, MUFA 6-65 %, total PUFA 4-81 %, n-6 PUFA 3-70% and n-3 PUFA 1-70 %. Diet PUFA included only essential fatty acids 18 : 2n-6 and 18 : 3n-3. The balance between n-3 and n-6 PUFA (PUFA balance) in the diet ranged from 1 : 99 to 86 : 14% n-3 PUFA:n-6 PUFA. The slope of muscle phospholipid composition plotted against diet composition quantifies the response of muscle membrane composition to dietary fat (0, no response; 1, complete conformity with diet). The resulting slopes were 0·02 (SFA), 0·10 (PUFA), 0·11 (MUFA), 0·14 (n-3 PUFA) and 0·23 (n-6 PUFA). The response to PUFA balance was biphasic with a slope of 0·98 below 10% diet PUFA balance and ...
Predicting fatty acid composition of beef cattle at slaughter using weaner data would enable an early selection decision thereby saving time and costs associated with progeny testing. The aim of this study was to examine genetic and phenotypic correlations between triacylglycerol fatty acid composition at weaning and slaughter. Subcutaneous fat between the 12th and 13th rib interface was biopsied from 324 weaner calves sired by Angus, Belgian Blue, Hereford, Jersey, Limousin, South Devon and Wagyu. Fat from the same anatomical site was sampled from their carcasses at slaughter and analysed for fatty acids by gas-liquid chromatography. Statistical analysis was by Mixed Model and Maximum Likelihood procedures of Harvey (1990) after adjusting for genotype, sire nested within genotype, sex and location. Results indicated strongly positive genetic correlations between biopsy and carcass stearate (18:0), oleate (18:1n-9), total monounsaturated fatty acids (MUFA) and delta-nine desaturase enzyme index ...
The aim of this thesis was to investigate how dietary fatty acids affect the risk for cardiometabolic disease, i.e. cardiovascular disease (CVD), type 2 diabetes and obesity. The overall hypothesis was that unsaturated fatty acids and especially the predominant polyunsaturated fatty acid (PUFA) linoleic acid (LA), 18:2n-6, would decrease cardiometabolic risk compared with saturated fatty acids (SFAs), in line with current recommendations to partly replace dietary SFA with PUFA.. Papers I and V were observational studies based on the community-based cohort Uppsala Longitudinal Study of Adult Men (ULSAM). Adipose tissue fatty acid composition was determined as biomarker for dietary fat intake. Studies II, III and IV were randomised short-term interventions on human volunteers, in which different dietary fats were provided to the participants.. In 71-year-old men, adipose tissue LA and α-linolenic acid (18:3n-3) were associated with insulin sensitivity (euglycaemic clamp), although this ...

N2 - In order to manipulate the physical properties of the macrophage membrane, methods were developed which potentiated the incorporation of exogenously supplied fatty acids into membrane lipids. Chromatograms of macrophages which were grown in the presence of a variety of fatty acids demonstrated that exogenously supplied unsaturated fatty acids (palmitoleic, oleic, elaidic, linoleic, linolenic and arachidonic acids) were readily incorporated into the cells and selectively altered the fatty acyl composition of macrophage phospholipids. Up to 38% of the total cellular phospholipids were found to be derived from the exogenously added fatty acid supplements. The incorporation of the different fatty acids into cellular phospholipids had striking effects on cellular phagocytic activity. These effects were found ...
In the category, there can be observed a trend for the toxicity of aquatic invertebrates. This is related to the toxicity mode of action (narcosis). Thus, a linear dependence on log Kow is expected. The highest toxicity was determined for methyl laurate (CAS 111-82-0, fatty acid chain length C12). In the GLP-study (Ministry of the Environment of Japan, 2006) according to OECD 202 the EC50 (48h) was determined as 0.255 mg/L for Daphnia magna. The toxicity decreases with shorter and longer chain length of the fatty acids. For methyl decanoate (CAS 110-42-9, fatty acid chain length C10), a lower toxicity for Daphnia magna was estimated. In one GLP-study (Bouwman, 2010) according to OECD 202 an EC50 of 1.1 mg/L was determined for methyl decanoate. Two QSAR-calculations for methyl octanoate (CAS 111-11-5, fatty acid chain length C8) yielded LC50 of 5.6 mg/L (ECOSAR, 2010) and LC50 = 11.6 mg/L (von der Ohe, 2005). The more conservative of the two values was accepted as the key value, what is ...
The intramuscular fat deposition and the fatty acid profiles of beef affect meat quality. High proportions of unsaturated fatty acids are related to beef flavor and are beneficial for the nutritional value of meat. Moreover, a variety of clinical and epidemiologic studies showed that particularly long-chain omega-3 fatty acids from animal sources have a positive impact on human health and disease. To screen for genetic factors affecting fatty acid profiles in beef, we initially performed a microsatellite-based genome scan in a F2 Charolais × German Holstein resource population and identified a quantitative trait locus (QTL) for fatty acid composition in a region on bovine chromosome 27 where previously QTL affecting marbling score had been detected in beef cattle populations. The long-chain acyl-CoA synthetase 1 (ACSL1) gene was identified as the most plausible functional and positional candidate gene in the QTL interval due to its direct impact on fatty acid metabolism and its position in the QTL
We investigated the potential of using multivariate factor analysis to extract metabolic information from data on the quantity and quality of milk produced under different management systems. We collected data from individual milk samples taken from 1,158 Brown Swiss cows farmed in 85 traditional or modern herds in Trento Province (Italy). Factor analysis was carried out on 47 individual fatty acids, milk yield, and 5 compositional milk traits (fat, protein, casein, and lactose contents, somatic cell score). According to a previous study on multivariate factor analysis, a variable was considered to be associated with a specific factor if the absolute value of its correlation with the factor was ≥0.60. The extracted factors were representative of the following 12 groups of fatty acids or functions: de novo fatty acids, branched fatty acid-milk yield, biohydrogenation, long-chain fatty acids, desaturation, short-chain fatty acids, milk protein and fat contents, odd fatty acids, conjugated ...
Abstract: Seasonal variations of fatty acids were studied in the lipid fractions of the bivalve mollusk, Saccostrea cucullata, at the intertidal zone of Chabahar bay in the northern part of Oman Sea (Iran). Samples were collected in rocky shores between two stations. The analysis were carried by GC/MS chromatography. Thirteen fatty acids were identified, of which, the most important saturated fatty acids (SFA) were 14:0, 4, 8, 12 tri Me- 13:0, 16:0 and 18:0, the mono unsaturated fatty acids (MUFA) included 16:1n-9, 18:1n-9 and 20:1n-11, the polyunsaturated fatty acids (PUFA) were linoleic acid 9,12 18:2 , eicosapentaenoic acid EPA 20:5n-3 and arachidonic acid 20:4n-6.Variability of the fatty acid components were studied in four seasons. Maximum percentage level in Saccostrea cucullata for 14:0, 4, 8, 12 tri Me 13:0, 16:0 and 15:0 as saturated fatty acids was observed in summer, while for 18:1n-9, 20:1n-11 and 20:5n-3 (as unsaturated fatty acids) maximum concentration was observed in winter. The ...

Structural, energetic, biochemical, and ecological information suggests that germination temperature is an important selective agent causing seed oils of higher-latitude plants to have proportionately more unsaturated fatty acids than lower-latitude plants. Germination temperature is predicted to select relative proportions of saturated and unsaturated fatty acids in seed oils that optimize the total energy stores in a seed and the rate of energy production during germination. Saturated fatty acids store more energy per carbon than unsaturated fatty acids; however, unsaturated fatty acids have much lower melting points than saturated fatty acids. Thus, seeds with lower proportions of saturated fatty acids in their oils should be able to germinate earlier and grow more rapidly at low temperatures even though they store less total energy than seeds with a higher proportion of saturated fatty acids. Seeds that germinate earlier and grow more rapidly should have a competitive advantage. At higher ...
The objective of the present study was to investigate the mobilization of individual fatty acids from human white fat cells. Mammary adipose tissue from eight healthy non-obese women in their normal dietary state was collected, and isolated adipocytes were incubated with lipolytic agents. The mobilization of 34 individual fatty acids was measured by comparing the composition of non-esterified fatty acids (NEFA) with that of the triacylglycerols (TAG) from which they originated through lipolysis. Compared with TAG, NEFA were enriched in some polyunsaturated fatty acids with 18-20 carbon atoms. Conversely, the percentage of very-long-chain (20-22 carbon atoms) saturated and monounsaturated fatty acids was approx. 2 times lower in NEFA than in TAG. The relative mobilization (% in NEFA/% in TAG) of the most readily mobilized fatty acid (C20:5,n-3; 2.25) was more than 6-fold higher than that of the least readily mobilized (C22:1,n-11; 0.37). Relationships were found between the molecular structure of ...
Background Palmitic acid (16:0), stearic acid (18:0), palmitoleic acid (16:1n-7), and oleic acid (18:1n-9) are major saturated and mono-unsaturated fatty acids that are synthesized via de novo lipogenesis (DNL) or obtained from the diet. Circulating levels of these fatty acids are linked to several diseases including diabetes and heart disease. Prior family and twin studies suggest high heritability of circulating levels, but potential genes involved are unknown.. Objective To carry out a Genome-Wide Association Study (GWAS) to investigate genetic determinants of circulating levels of these fatty acids.. Methods GWAS in 5 population-based cohorts (n=8,961) of European ancestry. Each study conducted linear regression analysis using an additive genetic model. All analyses were adjusted for age, sex, site of recruitment, and principal components to account for possible population genetic substructure where appropriate. Study-specific results were combined using inverse-variance weighted ...
Omega-3 fatty acids are quite beneficial for human health. These play a vital role in lowering blood cholesterol, blood triglycerides and, hence, blood pressure. Omega-3 fatty acids are helpful in preventing heart diseases, skin diseases and auto immune disorders. The daily intake of 0.5 to 1.0 gram omega-3 fatty acids is recommended for an individual for a healthy life. The food industry is taking steps to return these healthful fatty acids to the human diets. In this regards, poultry meat and eggs can serve the purpose if enriched with omega-3 fatty acids. Laying hens have the ability to absorb and deposit dietary fatty acids without considerable modification in the composition. Thus, the lipid metabolism in the hens permits the fortification of eggs with omega-3 fatty acids by dietary supplementation to increase the provision of these fatty acids which are appropriate for human consumption. This book provides the necessary information about the enrichment of eggs with omega-3 fatty acids by ...

The major finding of the present study was that serum linoleic acid was inversely associated with the risk of total stroke, ischemic stroke, and more specifically lacunar infarction. These associations remained significant even after adjustment for known cardiovascular risk factors and the matching variables of age, sex, years of serum storage, and community. Further adjustment for other fatty acids such as saturated and monounsaturated fatty acids did not materially alter the relation with risk of total stroke and ischemic stroke. Serum saturated fatty acids were positively associated with the risk of total stroke, ischemic stroke, and lacunar infarction, but these associations disappeared when adjusted further for linoleic and monounsaturated fatty acids. The adjustment for these fatty acids may be unreliable because saturated fatty acids and linoleic acid were strongly correlated. However, the analysis is likely to be correct statistically because we verified that the relationship of ...
The aim of the present study was to examine the effects of feeding alpha-linolenic (ALA) acid on fatty acid composition and quality of bovine sperm and on antioxidative capacity of seminal plasma. Nine bulls (ALA bulls) were fed with 800 g rumen-resistant linseed oil with a content of 50% linolenic acid and eight bulls with 400 g palmitic acid (PA bulls). Sperm quality was evaluated for plasma membrane and acrosome intact sperm (PMAI), the amount of membrane lipid peroxidation (LPO), and the percentage of sperm with a high DNA fragmentation index (DFI). Fatty acid content of sperm was determined using gas chromatography. Total antioxidant capacity, glutathione peroxidase, and superoxide dismutase activity were determined in seminal plasma. Feeding ALA increased (P , 0.05) the docosahexaenoic acid (DHA) content in bulls whereas in PA bulls did not change. PMAI increased after cryopreservation in ALA bulls as well as in PA bulls during the experiment period (P , 0.005). LPO of sperm directly after ...
Novel findings of the current study include: 1) significant increase in fractional myocardial dietary fatty acid uptake in IGT+ individuals not explained by difference in age, body fat, central obesity markers, or sex; 2) an association between the latter myocardial metabolic abnormality and reduction in systolic and diastolic left ventricular functions and increased myocardial oxidative metabolism; and 3) no significant changes in liver and skeletal muscle dietary fatty acid uptake in IGT+ individuals. The present results extend the association between increased myocardial NEFA uptake and oxidation and IGT observed during fasting (16) to postprandial dietary fatty acids. In addition, we confirmed the findings of others of reduced subcutaneous abdominal and visceral adipose tissue fractional uptake of dietary fatty acids in abdominally obese individuals (17,18). We furthermore found a direct association between impaired relative dietary fatty acid uptake in abdominal subcutaneous adipose tissue ...
In this prospective study, we examined the fatty acid composition of phospholipids in serum of 394 subjects to determine the role of different types of fatty acids in the incidence of breast cancer.. Overall, we did not find an association between individual or total MUFA or PUFA and breast cancer risk. The only systematic finding was a significant positive association between serum SFA levels and breast cancer risk after menopause.. Our investigation was based on blood samples collected at baseline in a prospective cohort study. The major strength of this approach is that it is very unlikely that the fatty acid profile we measured could be influenced by the presence of undetected cancer. A study on reliability of fatty acid composition in human serum phospholipids in the NYUWHS cohort (38) showed that fatty acid levels in a single blood sample per subject have a good correlation with repeat measurements after a 2-3-year interval. The fatty acid composition of serum phospholipids can therefore ...
A new cyanobacterial strain was isolated and purified from salt Lake Balkhash, Kazakhstan. According to its morphological and ultrastructural characteristics, 16S rRNA sequence and the fatty acid profile, the strain has been classified as Cyanobacterium spp. and assigned as Cyanobacterium sp. IPPAS B-1200. The strain is characterized by a non-temperature inducible Δ9-desaturation system, and by high relative amounts of myristic (14:0-30%) and myristoleic (14:1Δ9-10%) acids. The total amount of C14 fatty acids reaches 40%, which is unusually high for cyanobacteria, and it has never been reported before. The remaining fatty acids are represented mainly by palmitic (16:0) and palmitoleic (16:1Δ9) acids (the sum reaches nearly 60%). Such a fatty acid composition, together with a relatively high speed of growth, makes this newly isolated strain a prospective candidate for biodiesel production.
The mitochondrial acyl-carrier protein (ACP) functions in the synthesis of fatty acids within the mitochondrial matrix. Fatty acids are elongated on the covalently bound 4-phosphopantetheine cofactor on ACP. ACP has a second essential function within the mitochondria in the biogenesis of iron-sulfur clusters. Cells depleted of ACP are impaired in FeS cluster formation throughout the cell. ACP is a stable subunit of the cysteine desulfurase (Nfs1) and Isd11 subcomplex that generates sulfide ions for FeS cluster formation. The FeS defect observed in cells depleted of ACP can be partially suppressed by overexpression of the mitochondrial iron transporter Mrs3. The stability of ACP is dependent of the iron status of mitochondria. Thus, the central role of Acp1 in mitochondrial fatty acid synthesis, lipoic acid formation and FeS cluster biogenesis suggests that these processes are tied to Fe availability within the mitochondria. ...
Abstract: Fatty Acid Effect on Carcass The Influence of Various Blends of Dietary Fats Added to Corn-Soybean Meal Based Diets on the Fatty Acid Composition of Broilers
The function of fatty acid biosynthesis in mitochondria has remained an enigma. In eukaryotic plants, synthesis of fatty acids occurs primarily in plastids such as chloroplasts, and products of this pathway supply acyl precursors for mitochondrial and other extraplastidial membranes. The discovery of ACP in plant mitochondria (4, 5) has raised the possibility that these organelles also participate in de novo fatty acid synthesis. However, ACP has been considered to have several other functions in metabolism, and, in mitochondria, ACP is reported to be one component of the respiratory electron transport chain (14). Thus, whether ACP participates in fatty acid synthesis in plant mitochondria and what function this pathway might have in any eukaryotic organism has been unclear. In this study, we have demonstrated that the de novo synthesis of fatty acids does occur in pea mitochondria, indicating that these organelles possess the complete set of enzymes needed to assemble fatty acids. The analysis ...
Phospholipid fatty acid composition and vitamin E levels in the retina of obese (fa/fa) and lean (FA/FA) Zucker rats.: We have compared the fatty acid compositi
One pathway by which endotoxemia and lipid peroxidation act in concert to promote alcoholic liver injury is via NF-κB. NF-κB is a ubiquitous transcription factor that is implicated in the activation of many genes, including those involved in alcoholic liver injury (May and Ghosh, 1997; Nanji et al., 1999). The results of this study confirm our previous finding that activation of NF-κB occurs in association with development of necroinflammatory changes in the liver (Nanji et al., 1999). In addition, we show that the reduction in necrosis and inflammation induced by treatment with saturated fatty acid is accompanied by a marked reduction of NF-κB activation. The saturated fatty acid-induced inhibition of NF-κB activation was accompanied by increased amounts of IκBα. The mechanism by which saturated fatty acids stabilize IκBα and suppress NF-κB activation remains to be elucidated, but a role for decreased levels of endotoxin and lipid peroxidation is likely. Although we did not, in the ...

1. The highest surface pressure of phosphatidylcholine monolayers allowing penetration of delipidated serum albumin decreased in the order dibehenoyl,distearoyl,dipalmitoyl=dimyristoyl. This pressure was not related to the area occupied or to the space available between the phospholipid molecules at the interface. 2. Penetration of albumin into yeast phosphatidylcholine monolayers was increased by adding a small percentage of long-chain anions (phosphatidic acid, dicetylphosphoric acid) to the film but only when the protein was below its isoelectric point (i.e. positively charged). 3. Stearylamine added to phosphatidylcholine monolayers had no effect on albumin penetration even when the protein was oppositely charged to that of the phospholipid/water interface. 4. The results are discussed in relation to the activation of certain phospholipases by anionic amphipathic substances.. ...
Medium-chain triglycerides (MCTs) are triglycerides whose fatty acids have an aliphatic tail of 6-12 carbon atoms. The fatty acids found in MCTs are called medium-chain fatty acids (MCFAs). Like all triglycerides, MCTs are composed of a glycerol backbone and three fatty acids. In the case of MCTs, 2 or 3 of the fatty acid chains attached to glycerol are of medium length. Rich sources for commercial extraction of beneficial MCTs include palm kernel oil and coconut oil. With regard to MCFAs, apart from the above listed straight chain (unbranched chain) fatty acids, side chain (branched chain) fatty acids also exist. Molecular weight analysis of milk from different species showed that while milk fats from all studied species were primarily composed of long-chain fatty acid (16 and 18 carbons long), approximately 10-20% of the fatty acids in milk from horses, cows, sheep, and goats were medium-chain fatty acids. Some studies have shown that MCTs can help in the process of excess calorie burning, ...
Beef semitendinosus muscles were collected from ten bulls carcasses and used to determine fatty acids changes with different thermal treatment, boiling or microwave cooking. The results obtained show variabilities of fatty acids profiles in neutral lipid (NL), polar lipid (PL) and total lipid (TL) fraction under different internal temperature (60°C, 70°C or 80°C). Generally, in NL fraction (mainly beef intramuscular fat), content of polyunsaturated fatty acids (PUFA) increased (P | 0.05) significantly with boiling compared with raw beef, however, content of monounsaturated fatty acids (MUFA) and PUFA unchanged (P | 0.05) with the method of microwave cooking. On considering health benefit, it is proposed that beef with abundant intramuscular fat were more suitable for being treated with boiling, not microwave cooking. In PL and TL fraction, content of PUFA decreased (P | 0.05) with boiling and microwave cooking comparing with raw beef. Ratios of P/S (PUFA to saturated fatty acid (SFA)) decreased in

Omega-3 fatty acids provide many health benefits, from reducing cardiovascular disease to improving mental health, and consumer interest in foods enriched with omega-3 fatty acids is increasing. Formulating a product enriched with these fatty acids that is stable and has an acceptable flavour is challenging. Food enrichment with omega-3 fatty acids provides an overview of key topics in this area. Part one, an introductory section, reviews sources of omega-3 fatty acids and their health benefits. Chapters in part two explore the stabilisation of both fish oil itself and foods enriched with omega-3 fatty acids. Part three focuses on the fortification of different types of foods and beverages with omega-3 fatty acids, including meat products, by the modification of animal diets and other methods, infant formula and baked goods. Finally, part four highlights new directions in the field and discusses algal oil as a source of omega-3 fatty acids and labelling and claims in foods containing omega-3 ...
Dairy cows with greater subcutaneous fat stores release greater concentrations of nonesterified fatty acids (NEFA) into the blood during the periparturient period. Large quantities of circulating NEFA alter circulating phospholipids (PL) fatty acid (FA) profile. Modified cellular FA profile effects immune cell function. The objective of this study was to determine the effect of elevated lipid mobilization during the periparturient period on serum, peripheral blood mononuclear cells (PBMC), and polymorphonucleocytes (PMN) NEFA and PL fraction and milk fatty acid (FA) profile, PBMC and PMN gene expression of selected markers of inflammation and production measures. Thirty-four cows were blocked by parity; treatment group received a high-energy prepartum ration. Control group received a normal-energy ration and monensin. In summary, increased subcutaneous fat stores altered the FA profile of serum, PBMC and PMN NEFA and PL fractions and milk as well as gene expression of PBMC in periparturient ...
In order to predict omega-6 and omega-3 fatty acids in the diet of humans, seventy-three pork back fat adipose tissue samples were measured with Raman spectroscopy directly on adipose tissue and on melted fat. Melted fat samples were, in addition, measured with Fourier transform infrared (FT-IR) spectroscopy. Gas chromatography analyses were conducted as the reference analysis. Partial least squares regression (PLSR) was used to calibrate and validate all models predicting omega-3 and omega-6 fatty acids contents from spectra. Omega-6 fatty acids in melted fat measured with FT-IR was predicted with a correlation coefficient (,i,R,/i,) of 0.93 and a root mean square error of cross-validation (RMSECV) of 1.61% of the total amount of fatty acids. Raman spectra measured on melted fat gave a prediction of omega-6 fatty acids with ,i,R,/i, = 0.97, and RMSECV = 0.99% of total amount of fatty acids. Omega-6 fatty acids were predicted with ,i,R,/i, = 0.94, and RMSECV = 1.50% of the total amount of fatty ...
Abstract Background Porcine fatty acid composition is a key factor for quality and nutritive value of pork. Several QTLs for fatty acid composition have been reported in diverse fat tissues. The results obtained so far seem to point out different genetic control of fatty acid composition conditional on the fat deposits. Those studies have been conducted using simple approaches and most of them focused on one single tissue. The first objective of the present study was to identify tissue-specific and tissue-consistent QTLs for fatty acid composition in backfat and intramuscular fat, combining linkage mapping and GWAS approaches and conducted under single and multitrait models. A second aim was to identify powerful candidate genes for these tissue-consistent QTLs, using microarray gene expression data and following a targeted genetical genomics approach. Results The single model analyses, linkage and GWAS, revealed over 30 and 20 chromosomal regions, 24 of them identified here for the first time, ...
Ever since the emergence of the hypothesis that linked the aetiology of schizophrenia with abnormal membrane phospholipids composition, an increasing number of evidences have suggested reduced membrane polyunsaturated fatty acids in patients with schizophrenia. This has led to a conduct of several studies to evaluate the efficacy of omega-3 fatty acid supplement in the modification of membrane phospholipids and treatment of schizophrenia. The two main omega-3 fatty acid classes, EPA and DHA, play a vital role in membranes. This project work reviews omega-3 fatty acid studies and summarizes their outcomes. Eight original articles (nine studies) were reviewed. Six out of nine studies measured RBC membrane fatty acids levels and all six studies reported a significant increase in EPA after EPA supplement. Two studies reported increased DHA post omega-3 fatty acid and DHA supplement, respectively. One study observed a dose-dependent increment in DHA after EPA supplement. Improved symptoms were ...
The main findings in the present study were the differences in the fatty acid profiles of skeletal muscle phospholipids and triglycerides between the TRA group and the UNT group despite their similar dietary fatty acid composition. The fatty acid pattern in muscle phospholipids is probably partly genetically determined (4) but has also been shown to be influenced by environmental factors such as diet (2, 3) and physical activity (1, 19, 35). In the present study, the fatty acid composition of skeletal muscle was determined after 8 wk of diet with a controlled fatty acid composition. According to the food records, the study groups had similar proportions of fatty acids in the diet both at baseline and during the standardized period. The compliance to the controlled diet was verified by the similarity between TRA and UNT groups regarding the fatty acid compositions of serum cholesterol esters and serum phospholipids. Thus the observed dissimilarity in the fatty acid profile of skeletal muscle was ...
