Algae are a significant part of biodiversity and studies on their bioactive compounds are numerous. The aim of this work was to study the fatty acid profile of Cystoseira sauvageauana and Laurencia pinnatifida collected from the Algerian coast. Different conventional and alternative methods were used for lipids extraction and GCMS analysis for fatty acids methyl esters identification. The lipids content was low (<1%) for the two species while the highest yield was obtained by Folch method assisted with a pulsed electric field. The identified fatty acids in both species ranged from C14 to C20 carbon atoms, of which palmitic acid was the major compound. Regarding polyunsaturated fatty acids, in C. sauvageauana arachidonic acid (C20:4) was the major constituent in extraction methods using the chloroform: methanol mixture as solvent, while in the method using hexane, linoleic acid (C18:2) was found as the main constituent. In L. pinnatifida, eicosapentaenoic acid (C20:5) was the major fatty acid followed by arachidonic acid. In comparison between the two species the best polyunsaturated fatty acids/saturated fatty acids ratio was found in ultrasound assisted methods in C. sauvageauana. The omega-6/omega-3 ratio was considered satisfactory for both species; however, it was better in L. pinnatifida. The obtained results showed the influence of the solvent and the extraction method on the total lipid yield and the fatty acids composition in algal extracts. In addition, these two species could find an application in the field of food and pharmaceuticals.

Microalgae has been getting broad attention of researchers and investors lately, especially when discussing on healthy food and energy sources for the future. In this study, twelve samples of mixed microalgae from outdoor ponds were analyzed for their fatty acid compositions. The potential of microalgae to solve variety of world’s problems was not realized because of bottleneck in microalgal supplies at reasonable cost. Therefore, the objective of this study is to determine fatty acid profiles of mixed microalgae from tilapia fish ponds. The study was conducted in Tapak Ternakan Ikan, Taman Pertanian Universiti and Department of Biology, Faculty of Science, Universiti Putra Malaysia. Mixed microalgae were extracted for their lipids with methanol: chloroform mixture and after transesterification, the fatty acid methyl ester were analyzed using gas chromatography equipped with flame ionization detector. Results showed that saturated was the major constituent fatty acids. The average percentages of saturated fatty acids, monounsaturated fatty acids, and polyunsaturated fatty acids obtained were 45.62 ± 1.37%, 20.05 ± 1.14%, and 34.33 ± 3.17% respectively. The most dominant fatty acid profiles were C18:3n3 (α-linolenic acid) and C16:0 (palmitic acid), with the overall percentages of 19.97% and 19.40% respectively. The fatty acid profiles of mixed microalgae was good with a decent balance of saturated, monounsaturated and polyunsaturated fatty acids.

AbstractThis study investigated the efficiency of growth and the carcass characteristics of 24 Greyface (Border Leicester × Scottish Blackface), 24 Texel (12 purebred and 12 Texel × Texel-Greyface) and 24 Rouge (12 purebred and 12 Rouge × Rouge-Greyface) lambs finished on the same level of feeding. The efficiency of live-weight gain (kg/MJ) was higher in Greyface compared with Texel lambs (P< 0·01). The efficiency of empty body-weight gain (kg/MJ) was higher in Greyface (P< 0·01) and Rouge (P< 0·05) compared with Texel lambs. The efficiency of carcass gains (kg/MJ) tended to be higher in Greyface and Rouge compared with Texel lambs (P= 0·07). The efficiency of non-carcass component gains (kg/MJ) was also higher in Greyface compared with Texel lambs (P0·05). Carcass water, protein, lipid and ash gains did not vary significantly between the genotypes, however carcass energy gain tended to be higher in Greyface and Rouge compared with Texel lambs (P= 0·08). The relative proportions of water, protein, lipid and ash in carcass gains did not vary significantly between the genotypes. At the end of the experiment carcass water content was higher in Texel compared with Greyface lambs (P< 0·05) and carcass ash content was lower in Texel compared with Greyface (P< 0·01) and Rouge (P< 0·05) lambs. The concentration of saturated fatty acids was higher in Greyface compared with Rouge lambs (P< 0·001) and higher in Rouge compared with Texel lambs (P< 0·05). Monounsaturated fatty acid concentrations were higher in Rouge compared with Greyface lambs (P< 0·05) and higher in Texel compared with Rouge lambs (P< 0·001). Polyunsaturated fatty acid concentrations were higher in Rouge and Texel compared with Greyface lambs (P< 0·01). The ratio of n-6:n-3 fatty acids was lower in Rouge compared with Greyface lambs (P< 0·05).The efficiency of empty body gain was higher in male compared with female lambs (P< 0·05). Carcass water (P< 0·01) and protein (P< 0·05) gains were higher in male lambs. At the end of the experiment male carcasses contained a higher content of water (P< 0·05), protein (P< 0·01) and ash (P= 0·07), and a lower lipid (P< 0·05) and energy (P< 0·001) content. Carcass lipids from male lambs contained a higher concentration of polyunsaturated fatty acids (P< 0·001) and tended to contain a lower concentration of saturated fatty acids (P = 0·06).

Obese adolescents have high concentrations of saturated fatty acids and low omega-3 long-chain polyunsaturated fatty acids (LCUFAs) in plasma phospholipids. We aimed to investigate effects of omega-3 LCPUFA supplementation to obese adolescents on skeletal muscle lipids and glucose and insulin homeostasis. Twenty-five obese adolescents (14–17 years old, 14 females) completed a randomized double-blind crossover study supplying capsules containing either 1.2 g omega-3 LCPUFAs or placebo, for 3 months each with a six-week washout period. Fasting blood glucose, insulin, leptin, adiponectin, and lipids were measured. Intravenous glucose tolerance test (IVGTT) and euglycemic-hyperinsulinemic clamp were performed, and skeletal muscle biopsies were obtained at the end of each period. The concentrations of EPA, DHA, and total omega-3 PUFA in muscle phospholipids increased in both sexes. In the females, omega-3 LCPUFA supplementation improved glucose tolerance by 39% (P=0.04) and restored insulin concentration by 34% (P=0.02) during IVGTT. Insulin sensitivity improved 17% (P=0.07). In males, none of these parameters was influenced by omega-3 supplementation. Thus, three months of supplementation of omega-3 LCPUFA improved glucose and insulin homeostasis in obese girls without influencing body weight.

Eight Holstein cows with body weight 570 ± 43 kg and 60 ± 20 lactation days were distributed in a double Latin square design with four 21-day periods to determine the effects of feeding ground or whole flaxseed with or without monensin supplementation (0.02% on a dry matter basis) on fatty acid profile of butter stored for 15 and 45 days. Ground flaxseed supply, in comparison to whole flaxseed, reduced relative percentages of 16:0, cis7-16:1, 17:0, and cis10-17:1 but it increased those of cis9,trans11-18:2, cis3-18:3, and omega 3 fatty acids in butter fat, reducing relative percentage of medium-chain fatty acids and increasing the content of polyunsaturated fatty acids. Supplementation with monensin increased relative percentages of cis9,trans11-18:2 and tended to increase relative percentage of 17:0 and decrease that of saturated fatty acids in butter. Butter from cows fed diet with monensin presented lower relative percentages of cis 6-20:4. Relative percentages of cis 9-16:1, cis10-17:1, 18:0, trans11-18:1, cis9-18:1, cis3-18:3, cis6-20:4 in butter stored for 15 days were higher than those stored for 45 days and the relative percentages of cis3-20:5 tended to decrease with the increase of storage period. As a result, relative percentages of saturated fatty acids and medium-chain fatty acids increased with storage time, while those of monounsaturated and long-chain fatty acids decreased. Butter enriched with polyunsaturated fatty acids may have a shorter shelf life due to the negative effect of storage on fatty acid profile which may cause oxidation and rancidity.

Background and Aim: Flushing with the manipulation of fatty acids, particularly polyunsaturated fatty acids, like linoleic and α-linolenic acids in the ration, is a strategy to raise the nutritional status of the female mammals to improve ovarian function and follicle development. This study was designed to investigate the effectiveness of flushing supplementation with different types of polyunsaturated and saturated fatty acids in stimulating follicle growth and development during estrus in Ettawa Grade does with a low initial body condition score (BCS ≤2). Materials and Methods: Eighteen Ettawa Grade does in the second parity, with an average body weight of 32.11±2.19 kg, were divided into three groups according to the fatty acid supplemented to their ration: (i) About 2.8% lauric acid flushing (group); (ii) 2.8% linoleic acid flushing (LA group); and (iii) 2.8% a-linolenic acid flushing (ALA group). The ration was formulated to be isocaloric (total digestible nutrient = 77%) and isonitrogenous (crude protein = 15%). The experiment was conducted for 35 days; that is, 14 days for acclimatization and synchronization of the estrous cycle and 21 days for fatty acid flushing until the appearance of the next estrus. A completely randomized design was applied. Results: According to the results, none of the different fatty acids in the ration affected the nutrient intakes, BCSs, average daily gains, and plasma glucose, cholesterol, and progesterone concentrations of the three groups of does. However, the BCSs (by 0.8-0.9) and the plasma cholesterol concentrations were higher after fatty acid flushing for 21 days than before the flushing period. The ALA group had the highest number of large-sized preovulatory follicles, whereas the LAURIC group had the highest plasma estradiol concentration during estrus. All three groups had similar plasma progesterone concentrations during estrus after fatty acid flushing. Conclusion: Flushing supplementation with 2.8% ALA from flaxseed oil gave the best results in terms of stimulating the highest number of large-sized preovulatory follicles in Ettawa Grade does.

The aim of this work is to study the possibility of using blood serum (BS) fatty acids (FA) and erythrocytes (ER) as diagnostic markers of the severity of NAFLD. Materials and methods. We examined 52 patients with NAFLD (51.8 ± 3.9 years), confirmed by the NLFS index, and 20 apparently healthy men (49.2 ± 4.5 years). The degree of liver fibrosis was established by indirect elastometry (FibroScan® 502 Echosens, France). 27 patients had an initial degree of fibrosis (F0-1), 25 had severe fibrosis (F2-4). The study of the composition of fatty acids of Er and BS was carried out using a GC / MS system based on three Agilent 7000B quadrupoles (USA). Results. Significant differences in the levels of fatty acids in blood serum and erythrocyte membranes in patients with NAFLD were revealed, associated with the degree of fibrosis and necroinflammatory activity. To distinguish between mild and severe fibrosis in NAFLD, the levels of saturated fatty acids (myristic, pentadecane, margarine) and omega-3 PUFAs (eicosapentaenoic, docosapentaenoic, docosahexaenoic) were found to be significant (p = 0.002-0.0003). Saturated and monounsaturated FAs (palmitelaidic, palmitoleic, vaccenic) played a key role in differentiating the degree of necroinflammatory activity (minimal versus pronounced) (p = 0.03-0.005). The created diagnostic panels (FA of blood serum and erythrocyte membranes) made it possible to differentiate patients with NAFLD with varying degrees of fibrosis. Correlations of FA levels in erythrocyte membranes and blood serum with manifestations of metabolic syndrome, indicators of liver damage in patients with NAFLD were revealed. Conclusions. The established differences in fatty acid profiles of blood serum and erythrocyte membranes in patients with NAFLD, associated with the degree of fibrosis, necroinflammatory activity, manifestations of metabolic syndrome and indicators of liver damage, should be considered as promising biomarkers for assessing the severity of NAFLD.
