متن کاملBiosynthesis of Unsaturated Fatty Acids by Bacilli
Significant relationships have been established between the initiation and rate of fatty acid A”-desaturase synthesis in Bacillus megaterium ATCC 14581 and controlled perturbations in culture temperature, cell growth, protein synthesis, and RNA synthesis. B. megaterium growing from inoculum at 35” contained neither unsaturated fatty acids nor the A5-desaturase responsible for their production. ...
متن کاملEfficiency of cloud condensation nuclei formation from ultrafine particles
Atmospheric cloud condensation nuclei (CCN) concentrations are a key uncertainty in the assessment of the effect of anthropogenic aerosol on clouds and climate. The ability of new ultrafine particles to grow to become CCN varies throughout the atmosphere and must be understood in order to understand CCN formation. We have developed the Probability of Ultrafine particle Growth (PUG) model to ans...
متن کاملUnsaturated 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...
