These A-B intermediate forms adopt the sugar pucker properties and/or the base conformation of both DNA forms. In one study, the characteristic C3'-endo pucker is found on the first three sugars of the DNA strand, while the last three sugars have a C2'-endo pucker, like B-DNA. [2]
Its favored conformation is at low water concentrations. A-DNAs base pairs are tilted relative to the helix axis, and are displaced from the axis. The sugar pucker occurs at the C3'-endo and in RNA 2'-OH inhibits C2'-endo conformation. [13] Long considered little more than a laboratory artifice, A-DNA is now known to have several biological ...
A sample nutrition facts label, with instructions from the U.S. Food and Drug Administration [1] Nutrition facts placement for two Indonesian cartons of milk The nutrition facts label (also known as the nutrition information panel, and other slight variations [which?]) is a label required on most packaged food in many countries, showing what nutrients and other ingredients (to limit and get ...
The side opposite to the sugar linked vertex is traditionally called the Watson-Crick edge, since they are involved in forming the Watson-Crick base pairs which constitute building blocks of double helical DNA. The two sides adjacent to the sugar-linked vertex are referred to, respectively, as the Sugar and Hoogsteen (C-H for pyrimidines) edges.
The double-helix model of DNA structure was first published in the journal Nature by James Watson and Francis Crick in 1953, [6] (X,Y,Z coordinates in 1954 [7]) based on the work of Rosalind Franklin and her student Raymond Gosling, who took the crucial X-ray diffraction image of DNA labeled as "Photo 51", [8] [9] and Maurice Wilkins, Alexander Stokes, and Herbert Wilson, [10] and base-pairing ...
Carbohydrate NMR spectroscopy is the application of nuclear magnetic resonance (NMR) spectroscopy to structural and conformational analysis of carbohydrates.This method allows the scientists to elucidate structure of monosaccharides, oligosaccharides, polysaccharides, glycoconjugates and other carbohydrate derivatives from synthetic and natural sources.

The 5 glucose stimuli that were given to each observer were multiplied by a factor that made the mean equal to 10. This served as a standardized scale across all 9 experiments. Using this method guaranteed the ratios of each observer's judgments and the slope of the sweetness function, S = kC^n (S: sweetness, C: concentration, k: relative ...
