• Alkanes are chemical compounds that consist only of hydrogen and carbon atoms and are bonded exclusively by single bonds without any cycles. (absoluteastronomy.com)
  • It is related to acidity measurements in most cases by pH = log 1/2[1/(H+)], where (H+) is the hydrogen ion concentration in gram equivalents per liter of solution. (lookformedical.com)

  • The degradation of medium-length ones by Pseudomonas putida starts from the alkane hydroxylase, this enzyme is made up of three components: the membrane-bound oxygenase component and two soluble components called rubredoxin and rubredoxin reductase. (wikipedia.org)
  • The primary route of degradation for alkanes is to the alcohol. (europa.eu)
  • Although the introduction of aliphatic substituents normally alters the location in the molecule where the initial microbial attack takes place, the eventual degradation products should not be significantly different. (europa.eu)
  • It was released as the draft document Evidence on the Carcinogenicity of 1,3-Hexachlorobutadiene in August 2000. (nih.gov)
  • At their November 16, 2000 meeting the Committee, by a vote of none in favor and six against, did not find that 1,3-hexachlorobutadiene had been "clearly shown through scientifically valid testing according to generally accepted principles to cause cancer. (nih.gov)
  • The major difference between the metabolism under aerobic conditions of alkanes and isoalkanes relates to the impact of the branching on the rate of metabolism (Fritsche and Hofrichter, 2000). (europa.eu)
  • Hydrocarbonoclastic bacteria have two fundamental characteristics: (1) specific membrane-bound dioxygenases and (2) mechanisms for optimizing contact with water-insoluble hydrocarbons. (wikipedia.org)
  • For hydrocarbons with longer chain lengths, it is probable that the occurrence of formation of the secondary alcohol increases, (Kachholz and Rehm , 1977). (europa.eu)

  • 1,3-Hexachlorobutadiene was assigned a final priority of `high' carcinogenicity concern and placed on the Final Candidate list of chemicals for Committee review on August 6, 1999. (nih.gov)
  • The structures of high valent intermediates (Q in methane monooxygenase and X in ribonucleotide reductase) are debated since Fe-Fe distances of 2.5-3.4â Å were attributed to "open" or "closed" cores with bridging or terminal oxido groups. (bvsalud.org)

  • The major metabolic pathway for HCBD, and the one postulated to result in formation of the ultimate DNA reactive metabolite, is the GSH/mercapturate/b lyase pathway. (nih.gov)
  • Additional spreading takes place because (1) oil is usually spilled over a period of time and into a moving current, (2) wind, waves, and non-uniform currents diffuse and break up the slick, and (3) droplets periodi-cally disperse and resurface, tending to stretch the plume.
