An electron diffraction study has been made of oriented polyglycine I (the β modification of
polyglycine) and of single crystals grown from solution. The unit cell is very similar to that …

POLYGLYCINE II was shown to be a new structural form of polyglycine on the basis of its
characteristic X-ray diffraction pattern1 and infra-red spectrum1, 2. On the basis of the …

Re-examination of the known data on crystalline forms of polyglycine reveals that the crystal
modificationpolyglycine I'has two different three-dimensional structures depending on the …

Crystal structures are proposed for poly (l Ala-Gly-Gly-Gly) II (AGGG II) and poly (l Ala-Gly-
Gly) II (AGG II) on the basis of a study of small crystals by X-ray powder diffraction and, in the …

A tripeptide molecule, l‐alanyl‐glycyl‐glycine, crystallizes in the form of a left‐handed helix
with (ϕ, ψ)=− 83°, 170°. A pseudohexagonal packing arrangement and interchain hydrogen …

Recently, while revising the structure of collagen 6, we observed that a CH... O bond can be
formed between the neighbouring chains of its triple helix. A similar inter-chain CH... O bond …

The ultrastructural morphology and x‐ray and electron diffraction of poly (Gly‐Gly‐Ala) have
been studied. The polymer has two forms; the first, form I possesses a super‐folded cross‐β …

Packing energy calculations are made for two possible sheet structures of polyglycine I, ie
the antiparallel pleated and rippled sheets. They indicate that the rippled sheet is the more …
