Left & right a-heiix helical fiber fr 蟺-conjugated triphenylbenzene discotic stackingLu, R
The library of left- and right-handed 1-3 turn alpha-helical compounds reported herein project their amino acid side chains into very different regions of 3D space, constituting a unique and potentially valuable class of novel scaffolds. 展开 ...
Differential phase contrast microscopy under conditions of very slow cooling reveals the dominant self-assembly mechanism of a chiral diacetylenic phospholipid into multilamellar tubules to be the rapid growth of helical ribbons from spherical multilamellar vesicles. Surprisingly, in the first seconds of ...

An analysis of 636 helical segments, ranging in length from 4 to 32 residues, from 123 independent protein crystal structures reveals that helix termination by residues in left handed (alpha 1) helical conformations is a common occurrence. Gly and Asn residues are the most frequent alpha L helix...
摘要: PROBLEM TO BE SOLVED: To provide a left-hand/right-hand system compound transmission line in which a configuration is simplified by suppressing the number of ground plates into one and a value of a capacitor C is easily controlled while maintaining a thin shape....
