con·for·ma·tion

(kon'fōr-mā'shŭn),
The spatial arrangement of a molecule achieved by rotation of groups about single covalent bonds, without breaking any covalent bonds; the latter restriction differentiates conformation from configuration (as in anomers and related stereoisomers) where a bond or bonds must be broken in going from one form (configuration) to another. Conformation is one of the most important aspects of sugar chemistry and is basic to an understanding of the chemical properties of sugars. Compare: configuration.

From Table 1, it can be seen that the conformations 1 and 2 presented the most negative binding affinities, both with -3.8 kcal/mol and both involving oxygen and hydrogens in their interactions--with the hydrogen interactions shown in Figure 2.
States of the suspension are characterized by conformation tensors, c, and orientation tensors, a, describing the orientation and extension of the polymer molecules and the orientation of the nanofibers, respectively.
In this work, protein conformations are modelled using the nonisomorphic encoding proposed by Hoque et al.
Only qualitative agreement of the potential energy surface is needed with the physical parameters, because all that matters for the accurate determination of spatial conformations is that the torsional energy minima are in the correct places.
The density functional theory (DFT) is among the computational methods which offer a high accuracy for simulating distinct conformations and exploring properties based on electron transfer, besides changes in electron density in complex molecular systems.
Second, the 5'-GMP molecules take alternating C2'endo and Ci'-endo sugar pucker conformation along the helical strand.
By implementing this theory to the block copolymers, conformation of the polymer molecules as a function of distance between adjacent anchor chains can be determined.
As a result, they discovered that acute mastitis was more likely in ewes with poor udder conformation, teat lesions and inadequate nutrition in pregnancy, as well as those feeding twins or triplets.
These differences are mainly due to the different conformations that glutamate can take in complex with its respective original receptor nearly 22 cases analyzed.
Good conformations are obtained on the Blanc Bleu Belge cows double muscling fattening with corn silage: most have excellent (E) conformation (60.0%) followed by the superior conformation S (33.3%) and very good (U) conformation (6.7%) (Cabaraux et al., 2003).
When ligands bind to a specific subset of receptors, the ligands stabilize specific protein conformations, turning on (or off) molecular switches that control diverse cellular functions.
