Download or read book Effects of Dietary Linoleic Acid on Conversion of Omega 3 Fatty Acids to Long Chain Fatty Acids written by Elizabeth Flaherty and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: With the modern diet that is high in total fats, high in omega-6 fatty acids (FA), and low in omega-3 FA, there is a high prevalence of metabolic and cardiovascular disease. Certain dietary acids are beneficial, while others may contribute to these disease processes. Eggs are an important part of the human diet as they are protein and nutrient dense and are a good source of vitamins and minerals. It is possible to manipulate the nutrients and composition of FA in the eggs by modifying the balance of the hens diets. This makes them a good target for experiments with fatty acids (FA). A diet high in omega-3 (n-3) FA has many beneficial effects including plasma lipid reduction, reduction in some types of cancer mortality, anti-inflammatory effects, antiarrhythmic effects, antithrombotic effects, antiatheromatous effects, and less severe manifestations of autoimmune diseases and inflammatory diseases. Due to the benefits of n-3 FA, it is important to understand the effects of oleic acid and linoleic acid (LA; C18:2n-6) on the deposition of n-3 FA in egg yolks. The goals of the experiment are to determine the effect of these FA on deposition of ALA and VLC n-3 FA in yolks. It is hypothesized that LA will have a negative impact on the deposition of ALA in yolks as they compete for elongase and desaturase enzymes. Additionally, it is expected that oleic acid will also have a negative effect on n-3 deposition in yolks.Fifty hens were randomly assigned to one of five dietary treatments that included a control, two levels of high oleic safflower oil (HOSO; 2% and 4%), and two levels of high linoleic safflower oil (HLSO; 2% or 4%). All diets contained 4% flaxseed oil (FLAX) to provide -linolenic acid (ALA; C18:3n-3) as a substrate for synthesis of the very long chain omega-3(VLC n-3) FA. Egg samples were collected on day 0 and day 28 of the experiment and were analyzed for yolk weights and FA composition. Samples of adipose and liver tissue were collected on day 28 for FA analysis.Increasing dietary oleic acid (18:1n-9), provided by HOSO, had a positive effect on deposition of oleic acid in the yolk. Increased dietary linoleic acid (LA; C18:3n-6), provided by HLSO, had a negative effect on oleic acid deposition. HOSO and HLSO also negatively affected the deposition of ALA and VLC n-3 FA in yolks. This supports previous experiments that showed dietary n-6 FA had a negative effect on deposition of n-3 FA in yolks as a result of competition for the elongase and desaturase enzymes. The diet that is most conducive to developing a high n-3 fatty acid egg is a diet with a high level of ALA and a low level of oleic and linoleic acid.

Download or read book Effects of Dietary CLA on Fatty Acid Composition of Egg Yolks and delta 9 delta 6 and delta 5 Desaturase Activities of Livers of Laying Hens written by Irene Karantzeni and published by . This book was released on 2000 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conjugated linoleic acid (CLA) alters the fatty acid composition of chicken eggs. It also decreases hepatic stearoyl-CoA desaturase mRNA in HepG2 cells. The fatty acid composition of egg yolks was investigated as a function of amount of dietary CLA for laying hens. In addition, the activities of [Delta]9-, [Delta]6-, and [Delta]5- desaturases in hen liver were investigated as a function of CLA in the diet. Forty-eight Leghorn laying hens were assigned randomly to one of four dietary treatments formulated to contain 0, 1.25, 2.5, and 5.0% CLA. The fatty acid composition of yolk lipids was altered by dietary CLA, with a decrease in unsaturated fatty acids (palmitoleyl, linolenic, and arachidonic acids). The amount of CLA in eggs increased linearly with amount of dietary CLA. [Delta]9- and [Delta]5- Desaturase activities were lower in livers from hens fed the 5% diet than in livers of hens fed the 0% diet. [Delta]6-Desaturase activity was very low in livers of hens in all groups. In summary, dietary CLA decreases the amount of unsaturated fatty acids in chicken eggs with a corresponding decrease in desaturation activity in the hen liver microsomes.

Download or read book Arachidonic Acid in Cell Signaling written by Daniele Piomelli and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is about the arachidonic acid cascade, its biochemistry, its pharmacology, and its roles in signal transduction. Arachidonic acid may serve as an intracellular second messenger in many cell types, as well as precursor for biologically active molecules such as the eicosanoids (a family of oxygenated metabolites that may act as second messengers or as local mediators), and anandamide (an endogenous cannabinoid substance). Dysfunctions in the arachidonic acid cascade underlie a number of serious pathological conditions, making these biochemical pathways the target for drugs of clinical value.

This book was released on 1999-05-31 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food and raw material for its production was generally produced via the traditional agriculture. On the other hand, novel chemicals were manufactured in the laboratory or extracted from plant and animal sources. However, as the world population is steadily in creasing, there is a decrease in traditional agriculture productivity and concerns are also expressed over the damage inflicted to the environment and restrictions that might be en forced in food production. At the same time, there is an increasing demand for high qual ity agricultural products as well as for food ingredients related to both the traditional or newly discovered nutrients or phytochemicals. Trends and developments,~n the area of plant biotechnology and bioengineering has allowed manipulation of genes' !lnd/or insertion of new genes, thus production of trans genic plants. Starting from the introduction of agronomic traits, particularly stress resis tance to diverse environmental factors, process and sensory characteristics, food quality and production of novel varieties of plant-based products through genetic engineering, biotechnology is changing the,;agriculture and the concept of production of plant-ba~~d raw materials. Increasing attention is being paid on research for production of plants !pat can provide a wide array of food and non-food products. Perhaps the first non-food pro,d uct that plant biotechnology would achieve is production of large scale custom-designed industrial oils, but the list of chemicals is long, ranging" from oils and specific triacyl glycerols to biopolymers, enzymes, blood components, amo~g others.

This book was released on 2013-06-29 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: The annual meeting of the Perinatal Biochemical Group of the Spanish Biochemical Society held in Madrid on December 15-16, 1989, provided an excellent opportunity to bring together a group of distinguished investigators both from Spain and from abroad with a common interest in developmental endocrinology and biochemistry. The aim of the symposium was to present and discuss the most recent developments in the areas of endocrine and biochemical processes critical to normal growth and maturation of the newborn. To achieve a high degree of interaction among the participants, subject reviews as well as short communications were include in the program. The reviews provided in-depth information on selected important topics. The purpose of short communications was two fold: (i) to provide a forum to discuss on-going investigations on related areas; and (ii) to present opportunities for active participation by young investigators. This format proved very successful in generating fruitful discussions among the participants. Taken together the review chapters and the short communications have resulted in a coherent and unified subject presentation. Advances in biochemistry, molecular biology and cell biology have provided not only new and exciting experimental approaches but also have opened up new directions in the investigation of differentiation and developmental processes at cellular, molecular and biochemical levels during the early stages of growth and maturation. In recent years a wealth of information in these areas of development has emerged at a rapid rate.
