Conformations

Some articles on conformations, conformation:

Pyranose - Conformations
... leads to a total of 38 distinct basic pyranose conformations 2 chairs, 6 boats, 6 skew-boats, 12 half-chairs, and 12 envelopes ... The energy of these conformations can be calculated from quantum mechanics an example of possible glucopyranose interconversions is given ... The conformations of the pyranose ring are superficially similar to that of the cyclohexane ring ...
Types of Conformational Isomerism
... The three eclipsed conformations with dihedral angles of 0°,120° and 240° are not considered to be rotamers, but are instead transition states ... examples of conformational isomerism include Linear alkane conformations with staggered, eclipsed and gauche conformers, and Ring conformation Cyclohexane conformations with chair and boat conformers ... Carbohydrate conformation Atropisomerism- due to restricted rotation about a bond, a molecule can become chiral Folding of molecules, where some shapes are stable ...
Dry Lab - Distributed Computing
... labs have a slightly different approach, the main concept is to find, from a myriad of protein conformations, which conformation has the lowest energy or, in the case of Folding@Home, to find relatively ... that a specific protein will take a certain shape or conformation based on the amount of energy required for that protein to stay in that shape, this way of processing data is what is generally ... This analysis is done on an extraordinarily large number of different conformations, owing to the support of hundreds of thousands of home-based computers, in hopes to find the conformation of lowest possible ...
Tris(ethylenediamine)cobalt(III) Chloride - Stereochemistry
... Because of its nonplanarity, the MN2C2 rings can adopt either of two conformations, which are described by the symbols λ and δ ... The registry between these ring conformations and the absolute configuration of the metal centers is described by the nomenclature lel (when the en backbone lies parallel ... Thus, the following diastereomeric conformations can be identified Δ-(lel)3, Δ-(lel)2(ob), Δ-(lel)(ob)2, and Δ-(ob)3 ...
Stereoisomerism - Conformers
... Different conformations can have different energies, can usually interconvert, and are very rarely isolatable ... For example, cyclohexane can exist in a variety of different conformations including a chair conformation and a boat conformation, but, for cyclohexane itself, these can ... The boat conformation represents an energy maximum (and not a transition state) on the conformational itinerary between the two equivalent chair forms ...
