Low affinity calcium binding sites of the calcium transport ATPase of sarcoplasmic reticulum membranes.
Calcium binding sites having low affinity constants of less than 10(3) M-1 were titrated in native sarcomplasmic reticulum vesicles as well as in lipid deprived membranes and in the isolated calcium transport ATPase. Short time calcium binding measurements and the determination of the calcium binding heat allow to distinguish low affinity calcium binding sites located on the external surface of...
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 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 کاملRole of phospholipids in the calcium-dependent ATPase of the sarcoplasmic reticulum. Enzymatic and ESR studies with phospholipid-replaced membranes.
Three types of partially purified ATPase enzymes having different phospholipid contents and compositions have been prepared: (a) an enzyme whose phospholipid moiety has been replaced predominantly by dioleoyl lecithin (DOL-enzyme), with about the same phospholipid content as the original sarcoplasmic reticulum, (b) dipalmitoyl lecithin-replaced enzyme whose phospholipid content is 30% of that o...
