• While the functionalization of methionine, threonine, and isoleucine synthesis was unsuccessful, restoration of valine synthesis rendered mammalian cells partially independent of exogenous valine. (elifesciences.org)
  • Pyruvate oxidation - where did the hydrogen come from? (stackexchange.com)
  • Amino acid metabolism has extremely extensive effects in cancer cells, including, but not limited to, (1) establishing amino acid pools as building blocks, especially the production of non-essential amino acids … An overview of the metabolism of the sulfur amino acids is depicted in Fig. The outline of glycine metabolism is depicted in Fig. Oxidation via TCA cycle to produce energy (about 10-15% of body needs).

  • derived from glycolysis and pyruvate oxidation for carbohydrates and from beta oxidation of fatty acids. (easyomics.org)
  • In addition, 1.28% dietary methionine significantly induced fatty acid β-oxidation and lipolysis of the liver and muscle via increased carnitine palmitoyl transferase 1, peroxisome proliferator activated receptor alpha, lipoprotein lipase and lipase expression levels. (researchsquare.com)
  • Methanethiol (CH3 SH) - Is an organosulfur compound derived from cysteine oxidation. (metabolichealing.com)
  • At T1, the significantly more abundant enzyme-coding genes were related to threonine metabolism and those genes related to the glycolytic pathway, explained by the abundance of sugars in the medium. (frontiersin.org)
  • This pathway map also shows the Entner-Doudoroff pathway where 6-P-gluconate is dehydrated and then cleaved into pyruvate and glyceraldehyde-3P [MD:M00008]. (easyomics.org)
  • However, chronic alcohol consumption decreases GSH generation through cysteine deficiency by suppressing the methionine cycle and trans-sulfuration system, whereas it turns on an alternative defense pathway, such as the xCT transporter, to compensate for GSH shortage. (e-cmh.org)
  • Cystathionine beta-lyase (EC 4.4.1.8), also commonly referred to as CBL or β-cystathionase, is an enzyme that primarily catalyzes the following α,β-elimination reaction Thus, the substrate of this enzyme is L-cystathionine, whereas its 3 products are homocysteine, pyruvate, and ammonia. (wikipedia.org)
  • Lastly, the enamine tautomerizes into an imine that undergoes hydrolytic deamination to form pyruvate and ammonia. (wikipedia.org)
  • In garlic, the major flavor precursor is sulfur-alk(en)yl cysteine sulfoxide (ACSO, alliin), which is degraded by alliinase enzymes upon tissue disruption to give pyruvate, ammonia, and thiosulfinate. (springeropen.com)
  • In the liver, alanine transaminase transfers the ammonia to α-KG and regenerates pyruvate. (medmuv.com)
  • This is facilitated by glycolytic enzymes such as the M2 isoform of pyruvate kinase (PKM2) which diverts metabolites into PPP [ 6 ]. (degruyter.com)
  • In addition, S is present within many plant secondary metabolites possessing various functions in plant metabolism [ 1 ]. (biomedcentral.com)
  • At T2, the genes linked to the metabolism of ceramides and hopanoids lipids were clearly dominant, which are associated with the resistance of microbial species to extreme temperatures and pH values. (frontiersin.org)
  • In T3, genes linked to trehalose metabolism, related to the response to heat stress, dominated. (frontiersin.org)
  • For example, embryos produced in serum-containing conditions had a lower expression of genes related to metabolism while embryos produced in serum-free conditions showed aberrations in genes involved in lipid metabolism. (biomedcentral.com)
  • The transcriptome of embryos produced in serum-free conditions showed a greater resemblance to that of in vivo derived embryos, although genes involved in lipid metabolism were altered. (biomedcentral.com)
  • Oxygen deprivation in newborns leads to hypoxic-ischemic encephalopathy, whose hallmarks are oxidative/nitrosative stress, energetic metabolism alterations, nutrient deficiency, and motor behavior disability. (hindawi.com)
  • IUI alters cerebral metabolism because it causes a deficiency of oxygen and nutrients essential for maturing the neurochemical circuitry in the neonatal phase, particularly the glutamatergic and GABAergic pathways in the cerebral cortex [ 8 , 9 ]. (hindawi.com)
