網頁In this sense, more branched alkanes normally engender more steric destabilization energy than the normal ones. However, we have just touched upon one side of the“coin”. Simultaneously, there exist some attracting interactions between alky groups, stemming from electron correlation. 網頁Steric repulsion is also minimised in structures. In secondary structure, H bonds form between the amino acid peptde backbones. ...

網頁2011年12月31日 · It is believed that the steric-gearing effect of the 1,3,5-triethylbenzene template directs the binding elements toward the same face of the central ring, hence increasing the binding affinity. At the same time the 1,3,5-trimethylbenzene scaffold, without steric-gearing effects, has also been found to improve the binding affinities of hosts …
