• NADH
  • However, if either oxygen levels are insufficient (anaerobic conditions) or mitochondrial activity is absent, NADH must be reoxidized by the cell using some other mechanism. (encyclopedia.com)
  • enzymes
  • In particular, the present invention provides novel thermophilic organisms and thermostable enzymes capable of catalyzing the fermentation of glycerol to 1,3-propanediol. (lens.org)
  • An alternate approach is to use enzymes, either in vivo (i.e., in a microorganism) or in vitro, to catalyze the fermentation of glycerol to 1,3-propanediol. (lens.org)
  • In view of the potential advantages inherent in the use of biological methods and reagents to produce 1,3-propanediol, their exists a need for the development and identification of novel microorganisms and enzymes capable of converting glycerol and other carbon substrates to 1,3-propanediol having superior characteristics.

  • fatty
  • Fatty acids are released, between meals, from the fat depots in adipose tissue, where they are stored as triglycerides, as follows: Lipolysis, the removal of the fatty acid chains from the glycerol to which they are bound in their storage form as triglycerides (or fats), is carried out by lipases. (wikipedia.org)
  • Once freed from glycerol, the free fatty acids enter the blood, which transports them, attached to plasma albumin, throughout the body. (wikipedia.org)
  • reaction
  • Catalysis of the reverse reaction proceeds analogously, forming the same enediol but with enediolate collapse from the oxygen at C2. (wikipedia.org)
  • reactive
  • And a variety of microorganisms called obligate anaerobes cannot survive in the presence of oxygen, a highly reactive molecule. (tuscany-diet.net)
  • catalyzes
  • In the first step, a dehydratase catalyzes the conversion of glycerol to 3-hydroxy- propionaldehyde (3 -HP) and water (Equation 1). (lens.org)
  • form
  • The nucleophilic glutamate 165 residue of TPI deprotonates the substrate, and the electrophilic histidine 95 residue donates a proton to form the enediol intermediate. (wikipedia.org)
  • Besides the precisely placed glutamate and histidine residues to form the enediol, a ten- or eleven-amino acid chain of TPI acts as a loop to stabilize the intermediate. (wikipedia.org)
  • A second base deprotonates the hydroxyl group, leading to the collapse of the en-diol(ate) to form the 2-hydroxy 2-propenal enol intermediate along with dissocation of inorganic phosophate (-OPO3) through the cleavage of a C-O bond rather than an O-P bond. (wikipedia.org)
  • example
  • For example, when animals, but also athletes, perform high intense exercises, their need for ATP exceeds body's ability to supply oxygen to the muscle. (tuscany-diet.net)
  • precursor
  • By this I mean, I still have to interview a freshmen with april about her food choices, code and analyze all the data, start and finish a research paper on Intermediate Hyperglycemia ( the precursor to Diabetes Type 2), and write a response paper for minority health readings. (blogspot.com)
