This indicates that the substrate could easily access them once the glycosidic bond starts to break. WebConformational Analysis. It is important to note that in ethane there are three sets of bond eclipses taken pairwise. Since the total torsional strain is 3 kcal, it is usually considered that each pair of bond eclipses engenders 1 kcal of torsional strain. This kind of analysis is useful for estimating the torsional strain present in other ...
