Notizen:
X-ray diagrams from oriented films and fibers of poly-Nγ-carbobenzoxy-L-α,γ-diaminobutyric acid (PCLB) and of poly-Nδ-carbobenzoxy-L-ornithine (PCLO) have been examined. The conformation in the solid state for both polymers is that of an α-helix, 18/5 for PCLB and 11/3 for PCLO, respectively.Furthermore, while the PCLB molecules are packed in a trigonal lattice whose dimensions, on hexagonal axes, are a = 27.5 and c = 27.0 Å, the PCLO unit cell is monoclinic with a = 23.3, b = 22.7, c = 16.2 Å, and γ = 119.2°.
