• aldo-keto
  • Mining of transcriptome data and subsequent phylogenetic analysis led to identification of terpene synthases, pyrophosphatases, alcohol dehydrogenases, aldo-keto reductases, carotenoid cleavage dioxygenases, alcohol acetyltransferases, and aldehyde dehydrogenases, which are potentially involved in essential oil biosynthesis.

  • pentose
  • Activation of transketolase may shift excess glycolytic metabolites into the pentose phosphate cycle,accelerate the glycolytic flux, and reduce intracellular free glucose,thereby preventing its conversion to sorbitol. (diff.org)
  • protein
  • By feeding amino acids labeled with isotopic nitrogen to rats, it was discovered that the isotope was incorporated into many of the amino acids found in proteins of the liver and the gut, even though the total protein content of these tissues did not change. (britannica.com)
  • and d. selecting the compounds for which a modulation of the expression or of the activity of the isovaleryl-coenzyme A dehydrogenase protein, or a modulation of the expression of the gene thereof or a modulation of the activity of at least one of the promoters thereof, is measured in the sample or the mixture treated in b) compared with the untreated sample or with the untreated mixture.

  • 33. The in vitro method as defined by claim 32, wherein the compounds selected in step d) inhibit the expression or the activity of the isovaleryl-coenzyme A dehydrogenase protein, the expression of the gene thereof or the activity of at least one of the promoters thereof.

  • Vitamin C (ascorbic acid) acts in the strengthening of collagen structure, the principle protein of connective tissues (skin, cartilage, bone, etc. (wordpress.com)
  • lactic acid
  • Thus, during the stress of intense exercise, lactic acid appears in the blood , while glycogen, the form in which carbohydrate is stored in muscle, disappears. (britannica.com)
  • rather, they show only that compounds capable of yielding lactic acid are likely to be normal intermediates. (britannica.com)
  • Indeed, in the example, lactic acid is formed in response to abnormal circumstances and is not directly formed in the pathways of carbohydrate catabolism. (britannica.com)
  • Most cells will then carry out further reactions to 'repay' the used NAD + and produce a final product of ethanol or lactic acid . (wikipedia.org)
  • reaction
  • The resulting external aldimine can lose a proton, carbon dioxide, or an amino acid sidechain to become a quinoid intermediate, which in turn can act as a nucleophile in several reaction pathways. (wikipedia.org)
  • The overall reaction is exothermic (−12.0 kcal/mol), the second step being rate-limiting, with 12.6 kcal/mol for the activation energy Specificity is conferred by the fact that, of the four bonds of the alpha-carbon of the amino acid aldimine state, the bond perpendicular to the pyridine ring will be broken (Dunathan Stereoelectronic Hypothesis).

  • pyridine
  • PLP is retained in the active site not only thanks to the lysine, but also thanks to the interaction of the phosphate group and a phosphate binding pocket and to a lesser extent thanks to base stacking of the pyridine ring with an overhanging aromatic residue, generally tyrosine (which may also partake in the acid-base catalysis). (wikipedia.org)
  • molecule
  • Atom balance is maintained by the two phosphate (Pi) groups: Each exists in the form of a hydrogen phosphate anion (HPO42−), dissociating to contribute 2 H+ overall Each liberates an oxygen atom when it binds to an ADP (adenosine diphosphate) molecule, contributing 2 O overall Charges are balanced by the difference between ADP and ATP.
