Das Grundmodell der Regressionsanalyse,olypeptide chain reverses its overall direction. Using a hard-sphere model-building technique, Venkatachalam (1968) explored favorable H-bonded conformations of the three consecutive amide units of β turns (see Chou and Fasman, 1977, and references therein). The x-ray structural analysis of an incre

Das Grundmodell der Regressionsanalyse,nomenological theory based on classical electrodynamics. The quantum approach is preferable from a strict theoretical point of view, but is hard to implement in real calculations on molecules as large and complex as the nucleic acids. The classical theory is easier to implement, but has less theoret

,Binäre logistische Regression,bases are the chromophores that absorb ultraviolet light to undergo electronic transitions, which begin at 300 nm and continue into the vacuum UV region. In the case of DNA these bases are adenine (A), guanine (G), cytosine (C), and thymine (T); in the case of RNA the bases are A, G, C, and uracil (

Since protein secondary structures generally dominate CD spectra at wavelengths below 250 nm, the region from about 250 to 320 nm provides a valuab

In retrospect, it is amazing that so much useful structural information has been gleaned from ECD spectra which typically provide only a few independent, poorly resolved spectral features in these molecules.

Most of the spectrometers that measure CD have relied on conventional laboratory sources of broad-spectrum UV and visible light, particularly the high-pressure xenon arc. Around 1970, the frontiers of CD spectroscopy were extended into the vacuum UV by spectrometer
