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...
متن کاملHydroformylation 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...
متن کاملOxidation of unsaturated fatty acids
Plant leaf systems have been incubated under various conditions with uniformly labeled oleic acid, and the breakdown products identified by gas-liquid chromatography. Young green leaves of the castor plant (Ricinis gibsonii) and of the field pea plant (Pisum sutiuum) catabolize oleic acid by an oxygen-requiring pathway to heptadec-8-enaI which is then dehydrogenated by an NAD-coupled mechanism ...
متن کاملIsolation and determination methods for brain cerebrosides, hydroxy fatty acids, and unsaturated and saturated fatty acids *
A new method is described for the isolation of nearly pure total cerebrosides from fresh brain. Florisil columns are used to separate the cerebroside hydroxy and normal acids, in the form of their esters, and to separate the saturated and unsaturated esters of each group. The esters within each class are determined by gas chromatography, the hydroxy esters being run as the methyl ethers. Yields...
متن کاملUnsaturated 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...
