This compound has been shown to interact with water molecules in solution phase. 4-Deoxy-4-fluoro-a-D-glucopyranose is soluble in water and interacts with other carbohydrate molecules at an intermolecular level. 4DFA has an extrapolated melting point of about 216 degrees Celsius.

L-Ribose is a monosaccharide that is a constituent of ribonucleic acid, deoxyribonucleic acid and other compounds. It can be found in small quantities in most living organisms. L-Ribose has been modified to include fluorine atoms at the C2 position. The addition of fluorine atoms increases the stability of the molecule and its resistance to hydrolysis by esterases. L-Ribose has also been modified with methyl groups at the C3 position and glycosylation at the C4 position. This modification preserves the biological activity of L-Ribose and increases its water solubility. L-Ribose is used as a building block for custom synthesis, such as peptides or oligosaccharides.>>END>>

The 4-Toluoyl-a-D-thiomannopyranoside is a six-membered ring with a hydrogen atom at the center. The structure of this molecule is composed of two chains, each of which has four atoms in their backbone. There are also two conformations to the molecule, one that can be observed as a chair conformation and one that can be seen as a boat conformation. In the chair conformation, there are three bonds that form from the central carbon atom to other carbons on the same chain. These bonds are called alpha bonds, and they connect in a linear fashion. In the boat conformation, these three bonds form an angle of 120 degrees with each other and have staggered geometry. The alpha bonds in this case form an angle of 180 degrees with each other.
