Circular Dichroïsm

A novel homogeneous copolymer catalyst, poly(N-isopropyl-acrylamine-co-l-proline), possesses excellent activity and stereoselectivities. Even after ten cycles, the catalytic activity and stereoselectivities remained almost unchanged. The circular dichroism spectra of the copolymer catalyst are apparently different from the corresponding monomer.

Urinary Glycoprotein

Much work has been reported on the chemical, physical and morphological properties of urinary Tamm-Horsfall glycoprotein (THG). Although it was once reported that cystic fibrotic (CF) individuals had a defective THG, more recent data indicate that THG and CF-THG are similar if not identical.No studies on the conformational aspects have been reported on this glycoprotein using circular dichroism (CD). We examined the secondary structure of THG and derivatives under various conditions and have correlated these results with quaternary structure using electron microscopy.THG was prepared from normal adult males and CF-THG from a 16-year old CF female by the method of Tamm and Horsfall. CF female by the method of Tamm and Horsfall.
