objective: to modify yeild of milk fat and to improve fatty acids profile of milk fat with supplementation of the diet with fish oil enrich in omega-3 fatty acids, especially, eicosapentaenoic acid (epa) and docosahexaenoic acid (dha). design: clinical trial. animals: ten dairy cows (treatment group, n=5 and control group, n=5). procedure: different amounts of fish oil were fed to the treatment...

Background & Aim: Ocimum basilicum L. is belong to the Lamiaceae family which is cultivated as a culinary, industrial and medicinal plants in some countries from thousands years ago. The seed of this plant is rich in poly un-saturated fatty acids (PUFA) and produced a large amount of mucilage. Experimental: The oil of seed was extracted separately and converted to fatty acids...

abstract  introduction: this experiment was conducted to study the effects of different levels of flaxseed (0, 5, 10 and 15% of diet) and copper (in the form of cupric sulfate pentahydrate, 0 and 250 ppm of diet) on fatty acids and cholesterol in egg yolk of laying hens. methods: a total of 128 white leghorn layers aged 50 weeks were used in a factorial design and randomly assigned to 8 treatme...

Squids belong to the cephalopod family, which composes more than 5% of the total annual fishing volume of southern Iran as by- products; however, these do not have significant usage in Iran. This product was studied to extract the high-value products, i.e. marine oils rich in unsaturated multiple-band fatty acids from 50kg squid (Loligo loligo) obtained from Chabahar fishing port and transferre...

dog rose (rosa canina l.) is a wild native species in iran, with a significant genetic diversity. the purpose of this research was to study quantitative and qualitative characteristics of saturated and unsaturated fatty acids dog rose ecotypes in five habitats of isfahan province in 2014-2015. oil was extracted from seeds by using soxhlet apparatus; the fatty acid composition of oil was charact...

ten varieties of iranian soybeans are cultivated in different areas of the country; persia or sahar (sr), hill (hl), williams (wz), gorgan 3 (gn), clarke (kl), hawkey (hk), zaan (zn), harcor (hr), dare (dr) and simes (ss), grown in tropical regions. samples of these 10 varieties were obtained from the institute of plant and seed research. after sample preparation, their oils were extracted and ...

background: fatty acids are known to be critically important in multiple biological functions. phospholipid fatty acids of follicular fluid, an important microenvironment for the development of oocytes, may contribute to the women’s fertility and the efficacy of assisted reproduction techniques. the aim of this study was to investigate the effect of fatty acid composition of follicular fluid ph...

evaluation of four safflower (carthamus tinctorius l.) genotypes for oil content and fatty acidcomposition showed that oil content varied from 22.16 to 34.39% and the highest seed oilcontent was obtained from isfahan14 genotype (34.39%, respectively). among those fatty acidswere detected, linoleic acid (75.81- 77.86%) was the predominant fatty acid followed by oleic(12.57–13.75%), palmitic (6.0...

Although there is good evidence that the formation of new ester bonds may be catalyzed by lipolytic enzymes (1) it appears unlikely that such a mechanism could account for any very substantial net synthesis of triglyceride. The first evidence for a pathway of biosynthesis clearly different from the reversal of hydrolysis was provided by Tietz and Shapiro (2) who showed that the incorporation of...
