The object of this article is to review the developments in the field of intramolecularly H-
bonded extended and folded conformations in linear and cyclic peptide molecules. The …

Theoretical models for calculating the circular dichroism (CD) of biopolymers have been
constructed which allow the evaluation of the effects of geometric distortions within regular …

Chiral metal-organic frameworks (MOFs) have attracted a growing interest for their potential
use in energy technologies, asymmetric catalysis, chiral separation, and on a more basic …

Thesynthesis, characterization, and IR absorption, NMR, and CD properties of (L-Val)„host
tetra-, penta-, and hexapeptides containing an L-Ile, L-Ala, D-Val, L-Pro, or Aib guest residue …

The role of the conformationally constrained α‐aminoisobutyric acid (Aib) residue in the
aggregation and self‐assembly properties of oligopeptides is discussed, critically reviewing …

The asymmetric epoxidation of chalcone and other electron-poor olefins in a triphase system
(water-organic solvent-polyaminoacid) affords optically active oxiranes. The influence of the …

Trichogin GA IV, an 11-residue lipopeptaibol blocked at the N-terminus by an n-octanoyl
group and at the C-terminus by a 1, 2-amino alcohol (l-leucinol), extracted from the fungus …

Trichogin GA IV is a lipopeptaibol antibiotic characterized by the sequence nOct–Aib1–Gly–
Leu–Aib4–Gly–Gly–Leu–Aib8–Gly–Ile–Lol (nOct: n‐octanoyl; Aib: α‐aminoisobutyric acid; …

Abstract 1 H nmr studies are reported for the α, α-dialkylated α-amino acid, α-
aminoisobutyric acid homopeptides Z-(Aib) n Ot-Bun= 3-5, in chloroform solution. The …

Conclusion Because far fewer gaseous species have identifiable UV spectra than have
characteristic far-infrared or in-frared spectra, the potential of these spectral regions for both …
