Histological and fatty acids changes in Caspian salmon (SalmotruttacaspiusKessler, 1877) fed diets with different levels of vitamins E and highly unsaturated fatty acids (HUFA)

Response of laying hens to supplementation with various fatty acids when fed diets inadequate in protein and sulphur amino acids

Unsaturated fatty acids and pain.

Fatty acids, which are the essential nutrients for humans, are an important source of energy and an essential component of cell membranes. They also function as signal transduction molecules in a range of biological phenomena. Recently, an increasing number of physiologic and pharmacologic reports on fatty acids have improved our understanding of the association of fatty acids with certain dise...

Unsaturated fatty acids.

There is good scientific evidence that dietary fatty acid composition is involved in the aetiology of many diseases. Increasing the supply of n-3 polyunsaturated fatty acids (PUFA) may reduce the risk of CHD. Several scientific organizations (for example, see Department of Health, 1991, 1994; British Nutrition Foundation, 1992; Scientific Committee for Food, 1993; Food and Agriculture Organizat...

Unsaturated fatty acids in microorganisms.

Reports from this laboratory have described the existence of two different pathways for the biosynthesis of long chain monounsaturated fatty acids by microorganisms. In yeast, oleic and palmitoleic acids are formed oxidatively from the corresponding saturated acids by processes requiring molecular oxygen and TPNH (1). The same conversions have been demonstrated in AWycobacterium phlei (2), in t...

Effects of diets enriched in different sources of fatty acids on reproductive performance of Zel sheep

The present study evaluated the effects of diets enriched in saturated and polyunsaturated fatty acids (n-3and n-6) on reproductive indices, metabolic hormones and metabolites prior to ram introduction in oestrussynchronized ewes. Zel ewes (n=188) were assigned to 4 groups. Ewes in the control group (CON) did notreceive fat. Ewes in the 3 other groups received 3% oil/DM/day of palmolein oil (PL...

Hydroformylation of Unsaturated Fatty Acids

When hydroformylation of unsaturated fatty materials is done with rhodiu~-tripheny:lphosphine (or phosphite) catalysts, a number of advantages become apparent compared to cobalt carbonyl-catalyzed reactions. With rhodium, the reaction can be carried out (a) at pressures as low as 200 psi, (b) at each double bond location in a polyunsaturated fatty acid, and (c) in high yield and conversion. Sol...
