Circular Dichroic

The behaviour of D-glyceraldehyde in water, dimethyl sulfoxide, their mixtures and in 1,1,1,3,3,3-hexafluoro-2-propanol was studied by circular dichroism and UV spectroscopy in the 20-80°C temperature range. Fresh-prepared solutions of D-glyceraldehyde exist in a substantial measure in dimeric or oligomeric forms, which passed to a monomeric one. The different character of interaction of solvents with monomeric D-glyceraldehyde is discussed. The bisignate circular dichroic curves are associated with conformational equilibrium of rotamers. The presumption on their spatial arrangement is confronted with the quantum chemical calculation of the rotational strength.

Circular Dichroïsm

Circular dichroism of acyclic forms of D-fructose, L-sorbose, D-tagatose, and four deoxy derivatives of D-fructose has been interpreted from the point of view of the equilibrium of rotamers around the bond of the chromophore and chiral residue of the molecule. The conformational equilibrium manifested by the double-sign dichroic curve changes with constitutional, solvation, and temperature conditions. It can be characterized as a syn ⇌ anti equilibrium according to mutual orientation of the carbonyl and vicinal hydroxyl groups.

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.
