The chemical composition variations of the Indian mackerel (Rastrelliger kanagurta) from Karachi coast were investigated seasonally over the period of one year (2004-2005).  Moisture, crude protein, fat and ash contents varied from 70.11-74.41%, 16.02- 20.09%, 3.0-12%, and 0.89-1.35% respectively. The seasonal data indicated that the main fatty acids of the total lipid were C16:0, C16:1, C18:0,...

The membrane lipid and fatty acid compositions of red blood cells from a paramyotonia patient were investigated. Cholesterol and total phospholipid contents in paramyotonia were not different from control. Only the sphingomyelin content was lower, and thus the molar ratio of phosphatidylcholine/sphingomyelin was higher than normal. The major abnormality concerned the fatty acid pattern. In all ...

changes in the fatty acid composition and biochemical indices of mackerel (which has a substantial lipid content) and shark (which has negligible lipid content) fillets stored at - 18°c for up to six months were measured. lipid content was measured (6.35% and 1.38%) in mackerel and shark, respectively; however it decreased during frozen storage in both fish species. in analysis of fatty acids t...

BACKGROUND Fatty acids are substantial components of lipids and cell membranes in the form of phospholipids. This review consists of two parts. The present part aims at describing fatty acid classification, dietary sources and biological functions. The second part will focus on fatty acid physiological roles and applications in human health and disease. RESULTS In humans, not all fatty acids ...

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...

Shea butter is the edible fat extracted from the nut of African Shea tree (Vitellaria paradoxa). Consequence of having half of its fatty acids saturated, Shea butter melts at a very high temperature and will be a suitable raw material for margarine production. Margarine is a butter mimicry that is produced from vegetable oils and water. The production of margarine requires a solid fat. Hence hy...

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...

Numerous investigations have led to the point at which refined enzyme systems may be used to study the biosynthesis of saturated fatty acids (2, 3). The biosynthesis of unsaturated fatty acids has not been so thoroughly elucidated. Formation of unsaturated fatty acids has been observed experimentally in viva (4-9) and in vitro (10, 11) but several of these studies showed that incorporated radio...

BACKGROUND Patients with cardiovascular system diseases having their origin in arteriosclerosis require special dietetic treatment. Among many nutritional components, fats in the diet (both their quantity and quality) play a very important role in primary and secondary prevention of these diseases. OBJECTIVES The aim of the study was the estimation of total fats participation (saturated fatty...

The lipid compositions of barophilic bacterial strains which contained docosahexaenoic acid (DHA [22:6n-3]) were examined, and the adaptive changes of these compositions were analyzed in response to growth pressure. In the facultatively barophilic strain 16C1, phosphatidylethanolamine (PE) and phosphatidylglycerol (PG) were major components which had the same fatty acid chains. However, in PE, ...
