  • Structure
  • We have examined the effect of substituents on nicotine's structure, conformation , and chemical r~activity: A chemical model for nicotinic activity has been developed by a thorough evaluation of the methylation of these analogues, thereby simultaneousl~ quantifying the relative and absolute nitrogen nucleophilicities of these nicotinoids.

  • The skeletal and muscular structure is more important in herd bulls than in cows, however cows must also have good conformation and be in body condition in order to be deemed good, solid and high productive cows that are suitable for your breeding herd. (wikihow.com)
  • In the structure, STRADα adopted a conformation similar to that of an active kinase and bound an ATP molecule. (sciencemag.org)
  • Comparison of the structure of STRADα when bound to MO25α resembled that of CDK1 (cyclin-dependent kinase 1) bound to cyclin A and a complex between an active epidermal growth factor receptor (EGFR) and an EGFR in the inactive conformation, with the conformation characterized as "closed and active.

  • The following examples show how to set up alternate conformations for structure factor calculations as well as for empirical energy calculations. (yale.edu)
  • The concept of chromatin contact mapping, or determining the three-dimensional structure conformation and interactions of chromatin domains, is now a reality because of Chromatin Conformation Capture (3C) and subsequent methods born out of that approach. (abcam.com)
  • trans
  • The resonances corresponding to the cis and the trans conformations of the wild-type AHSP are labeled as c and t, respectively. (factbites.com)
  • A systematic increase of the gauche conformation relatively to the trans is found with decreasing polymer content both for the C-C and the C-O bonds that exist along the PEO backbone indicating that the severe confinement and the proximity to the inorganic surfaces results in a more disordered state of the polymer.

  • chains
  • The conformation of polymer chains under confinement is investigated in intercalated polymer/layered silicate nanocomposites. (mdpi.com)
  • Attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR) is utilized to investigate the conformation of the polymer chains over a broad range of temperatures from below to much higher than the bulk polymer melting temperature. (mdpi.com)
  • Whilst there are many alignment tools that optimize a global superposition, there is a need for the development of methods that align macromolecular structures in a way that is independent of the global conformations of the compared chains. (iucr.org)
  • change
  • Biopolymers, such as polynucleotides, polypeptides or polysaccharides, may change conformation in response to changes in their environment. (nature.com)
  • activity
  • Although lacking in kinase activity, crystal structures reveal that the pseudokinase STRADα adopts a conformation resembling that of an active kinase. (sciencemag.org)
  • case
  • In the case of conformation judging, where decisions are based solely on the quality of the dogs, a judge may modify the regular judging procedure to accommodate a disabled handler. (akc.org)
  • large
  • Light scattering offers non-invasive determination of conformation, in solution, over large and representative ensembles. (wyatt.com)
  • solid
  • Chemical shifts of amino acid carbons in the solid state in a beta-sheet conformation differ by as much as 8 ppm from those in an alpha-helix (Saito, 1986). (factbites.com)
  • model
  • Crystal structures of mammalian β-actin in which the nucleotide binding cleft is in the "open" and "closed" states can be used to model actin filaments in the ADP and ADP-P i conformations, respectively. (pnas.org)
  • relative
  • Automatically generated colour schemes corresponding to various residue-based scores are provided, which allow the assessment of the conservation of backbone and side-chain conformations relative to the local coordinate frame. (iucr.org)
  • examples
  • This chapter introduces two basic examples of direct electrical control of biomolecular conformation, namely, voltage-gated ion channels in excised, surface immobilized, biological membranes, and antibodies of the IgG type, immobilized on an electrode surface. (oreilly.com)
