Cayley's theorem, in principle, can be used in determining the isomers of alkanes lot, which was originally limited to the calculation of the number of isomers of manual calculation, the method of "drawing and counting." Graph structure of the alkane is a tree (the tree). By proving that the alkane is a tree graph of a satisfying E (G) = V (G) with a value of V (G) = 3n + 2 and E (G) = 3n +1, -...

2014 The effects of mixed phospholipid headgroup composition and the addition of small amounts of alkane were examined with respect to the lamellar (L03B1) to inverse hexagonal (HII) phase transition in phospholipidwater liquid crystals. X-ray diffraction was used to probe the lattices and determine the phases. It has been postulated that competition between hydration repulsion, lipid monolayer...

The Deepwater Horizon (DWH) blowout in the northern Gulf of Mexico represents one of the largest marine oil spills. Significant shifts in bacterial community composition in the water column correlated to the microbial degradation and utilization of oil hydrocarbons. Nevertheless, the full genetic potential and taxon-specific metabolisms of bacterial hydrocarbon degraders enriched during the DWH...

Alkane monooxygenases in Nocardioides sp. strain CF8 were examined at the physiological and genetic levels. Strain CF8 can utilize alkanes ranging in chain length from C(2) to C(16). Butane degradation by butane-grown cells was strongly inhibited by allylthiourea, a copper-selective chelator, while hexane-, octane-, and decane-grown cells showed detectable butane degradation activity in the pre...

Decades of research on the autooxidation of organic compounds have provided fundamental and practical insights into these processes; however, the structure of many key autooxidation intermediates and the reactions leading to their formation still remain unclear. This work provides additional experimental evidence that highly oxygenated intermediates with one or more hydroperoxy groups are preva...

The atmosphere of Titan, Saturn's largest moon, exhibits interesting UV- and radiation-driven chemistry between nitrogen and methane, resulting in dipolar, nitrile-containing molecules. The assembly and subsequent solvation of such molecules in the alkane lakes and seas found on the moon's surface are of particular interest for investigating the possibility of prebiotic chemistry in Titan's hyd...

Measurement of organic compounds in KarahaTelaga Bodas and Coso fluid inclusions shows there are strong relationships between H2 concentrations and alkane/alkene ratios and benzene concentrations. Inclusion analyses that indicate H2 concentrations > 0.001 mol % typically have ethane > ethylene, propane > propylene, and butane > butylene. There are three end member fluid compositions: type 1 flu...

alcanivorax borkumensis is a marine bacterium that has ability to grow on limited substrates that mainly is alkanes. the ability to use wide range of hydrocarbons is advantage of this bacterium to other marine community bacteria. a. borkumensis have two genetic systems for alkane biodegradation. the first system is alkane hydroxylase (alk-b1and alk-b2) and the second system is  cytochrome p450....
