Isotopic fractionation in proteins as a measure of hydrogen bond length.

If a deuterated molecule containing strong intramolecular hydrogen bonds is placed in a hydrogenated solvent, it may preferentially exchange deuterium for hydrogen. This preference is due to the difference between the vibrational zero-point energy for hydrogen and deuterium. It is found that the associated fractionation factor Φ is correlated with the strength of the intramolecular hydrogen bon...

Isotopic fractionation during peptide bond hydrolysis

Isotopic fractionation of nitrogen and carbon is considered during peptide bond hydrolysis. Theoretical considerations suggest that hydrolysis will enrich residual, unhydroiyzed protein in “N while r3C should be relatively unaffected. Preliminary experimental results support this conclusion, although further studies are reauired to auantifv the magnitude of this effect as a function of protein ...

Communication: Frequency shifts of an intramolecular hydrogen bond as a measure of intermolecular hydrogen bond strengths.

Infrared-ultraviolet double resonance spectroscopy has been applied to study the infrared spectra of the supersonically cooled gas phase complexes of formic acid, acetic acid, propionic acid, formamide, and water with 9-hydroxy-9-fluorenecarboxylic acid (9HFCA), an analog of glycolic acid. In these complexes each binding partner to 9HFCA can function as both proton donor and acceptor. Relative ...

Carbon and hydrogen isotopic fractionation during anaerobic biodegradation of benzene.

Compound-specific isotope analysis has the potential to distinguish physical from biological attenuation processes in the subsurface. In this study, carbon and hydrogen isotopic fractionation effects during biodegradation of benzene under anaerobic conditions with different terminal-electron-accepting processes are reported for the first time. Different enrichment factors (epsilon ) for carbon ...

Hydrogen and Oxygen Isotopic Fractionation During Heterotrophic Cellulose Synthesis

Hydrogen and oxygen isotopic fractionation relative to medium water for two different carbohydrate metabolic pathways leading to cellulose synthesis were measured. This was accomplished by analysing stable hydrogen and oxygen isotope ratios of water and cellulose for seedlings. The seedlings had been germinated and heterotrophically grown in closed vessels from species having starch (Triticum a...
