12 Δεκ 2019 · Only the hydrogens of the glucose ring form hydrogen bonds, with lengths varying between 1.6 and 1.8 Å, while the two hydrogens of the fructose ring, H3f and H4f, show a first neighbor water oxygen at a distance longer than 2 or 3 Å, respectively (Figure Figure5 5 A).

The bond between the oxygen and hydrogen atoms (O–H bond) in sugar (sucrose) gives the oxygen a slight negative charge and the hydrogen a slight positive charge. Sucrose is a polar molecule. The polar water molecules attract the negative and positive areas on the polar sucrose molecules which makes sucrose dissolve in water.
Table S1: Sample composition for the three experiments. Sucrose and Lactose \D samples: hydrogen belonging to OH groups (exchangeable) have been exchanged to deuterium, by cycles of solvation in D 2O and freeze-drying; CH groups (non-exchangeable) remain hydro-genated. Sucralose has been simply dissolved in water with di erent isotopic composition,
18 Δεκ 2019 · Sucrose in aqueous solution integrates into the water hydrogen bond network, bonding with water and other sucrose molecules, resulting in a more compacted solution (Starzak et al., 2000)....
4 Οκτ 1996 · Introduction With eight hydroxyl groups, three hydrophilic oxygen atoms, and fourteen hydrogen atoms, the sucrose molecule can readily interact through hydrogen bonding with water, molecules, and proteins.
4 Σεπ 2013 · I employ an exact statistical thermodynamic theory (Kirkwood–Buff theory) to calculate information regarding sucrose–water, water–water and sucrose–sucrose interactions solely from volumetric and osmometric data.
In the low water limit, sucrose forms multiple intramolecular hydrogen bonds, whereas trehalose remains unfolded, and thus has more of its hydrogen-bonding sites available for interactions with other molecules.
