WebRaman spectra of syndiotactic polypropylenes of different stereoregularity are reported. Spectra for ordered and disordered structures of these polymers were simulated using a small number of parameters. The features that occur in the 300 and 400 cm -1 regions can be used to assess chain tacticity. A quantitative determination of the racemic content of … WebBiochem/physiol Actions. Polyglycine exists in two forms, namely the polyglycine I (PGI) with anti-parallel β-sheet structure and polyglycine II (PGII) with extended 31-helix. It is a most flexible polypeptide with minimal steric hindrance and its solubility increases in the presence of lithium ions. [ 3] It is present in mammals and plants.
