  • Glycine
  • To find a possible explanation for the selective hepatic conjugation of bile acids with glycine or taurine, the N-acyl amidates of cholic acid and a number of amino acids and amino acid analogues were synthesized, and their susceptibility to hydrolysis by pancreatic juice, gastric juice, serum, or small intestinal mucosal enzymes was measured. (eurekamag.com)
  • These experiments indicate that glycine and taurine amidates of cholic acid differ from a number of other conjugates with neutral and basic amino acid in being resistant to hydrolysis by pancreatic and plasma carboxypeptidases. (eurekamag.com)
  • These data, together with other data indicating that bile acid conjugation greatly decreases passive intestinal absorption, indicate that a physiologic function of bile acid conjugation with glycine or taurine is to form surfactants that remain indigestible and rather nonabsorbable during digestion in the proximal small intestine.

  • 3. You generally titrate acids with bases but you cannot titrate amino acid (say glycine) directly with NaOH------Explain why? (scribd.com)
  • 2+2 (i) (ii) In the anion exchange chromatography the Glutamine being negatively charged binds to the anion and glycine being neutral elutes first. (scribd.com)
  • Has a pH-dependent electrogenic transport activity for small amino acids such as glycine, alanine and proline. (uniprot.org)
  • Pretreatment with benzoic acid had teet hing or no effect on glycine N-acyltransferase activity in either renal or hepatic tissue (James and Bend, Motirn. (design-citi.ru)
  • Proline
  • Alanine and leucine are strong helix-favoring residues, while proline is rarely found in helices because its backbone nitrogen is not available for the hydrogen bonding required for helix formation. (scribd.com)
  • metabolism
  • An important source of energy for muscle tissue, the brain and central nervous system, also strengthens the immune system by producing antibodies, helps in the metabolism of sugars and organic acids. (dynamicgreens.com)
  • transporters
  • Disorders associated with the malfunction of amino acid transporters reflect the variety of roles that they fulfil in human physiology. (biochemj.org)
  • Amino acid transporters that are integral parts of metabolic pathways reduce the function of these pathways. (biochemj.org)
  • accumulation
  • Their function as exchangers presumably relies on the active accumulation of amino acids through other mechanisms. (pnas.org)
  • This motif is necessary and sufficient for nucleolar localization of NIK, as judged by nuclear localization of mutant versions of the full-length protein and the fact that coupling of these seven amino acids to GFP also leads to accumulation in nucleoli. (biologists.org)
  • nucleotide
  • 7. A nucleic acid comprising a nucleotide sequence which encodes a recombinant fusion protein comprising two or more erythropoietin molecules. (google.com)
  • Sodium
  • A wide range of nutrients (e.g., amino acids, phosphorus, and lactate) are transported across the placenta mediated by secondary active transport, utilizing energy provided by ion gradients such as sodium, chloride, and protons [ 14 - 16 ]. (hindawi.com)
  • molecule
  • It turns out that the structural properties of an alanine molecule in aqueous solution can differ significantly from those in crystalline phase, these differences being mainly attributed to hydrogen bonding interactions. (edu.au)
  • Overall, our findings strongly suggest that the generally accepted approach of extending the structural information acquired from crystallographic data to a L-alanine molecule in aqueous solution should be used with caution. (edu.au)
  • Substantially purified Ror1 comprising a protein encoded by the nucleic acid molecule according to claim 1. (patentgenius.com)
  • selective
  • The results obtained on the individual reactive extraction indicated the possibility of the amino acids selective separation as a function of the pH value of aqueous solution and the acidic or basic character of each amino acid. (ad-astra.ro)
  • hydrogen
  • These amino acids participate in hydrogen bonding of protein structure. (scribd.com)
  • In particular, we found that the largest difference between the two alanine forms can be seen for the orientation and bond lengths of the carboxylate (COO-) group: in aqueous solutionthe C-O bond lengths appear to strongly correlate with the number of water molecules which form hydrogen bonds with the COO- group. (edu.au)
  • Furthermore, the hydrogen bond lengths are shorter and the hydrogen bond angles are larger for L-alanine in water as compared to crystal. (edu.au)
  • concentration
  • System A function also varies inversely with the concentration of extracellular amino acids as part of adaptive regulation and up-regulates with cell proliferation and hypertonic shock, suggesting additional homeostatic roles. (pnas.org)
  • The desired efficacious concentration of peroxycarboxylic acid may vary according to the product application (for example, ca. 500 ppm to 1000 ppm for medical instrument disinfection, ca. 30 ppm to 80 ppm for laundry bleaching or disinfection applications) in 1 min to 5 min reaction time at neutral pH.

  • form
  • Patients without bowel disease who form infant motrin for teething pain acid stones appear to have urine that is acidic most of the time (101). (design-citi.ru)
