The crystal structure is monoclinic with the / group. The crystal cell parameters are a = 1014.35 pm , b = 815.42 pm, c = 862.39 pm, β = 92.3556 ° , Z = 4. The cell volume is 0.71270 nm 3 , or about 0.178 nm 3 per molecule (which is a bit smaller than the typical volumes of other isomers).
In chemistry, a hexose is a monosaccharide (simple sugar) with six carbon atoms. [1] [2] The chemical formula for all hexoses is C 6 H 12 O 6, and their molecular weight is 180.156 g/mol. [3] Hexoses exist in two forms, open-chain or cyclic, that easily convert into each other in aqueous solutions. [4]

Skeletal structural formula of Vitamin B 12.Many organic molecules are too complicated to be specified by a molecular formula.. The structural formula of a chemical compound is a graphic representation of the molecular structure (determined by structural chemistry methods), showing how the atoms are connected to one another.

The program can read and write many file formats, other than its proprietary sketch file format (.skc) and can export PNG files. If SVG files are required, it is recommended that structure diagrams be exported as enhanced metafiles (.emf) which can be read by Inkscape and other image editors..
Because many compounds feature structurally similar six-membered rings, the structure and dynamics of cyclohexane are important prototypes of a wide range of compounds. [ 1 ] [ 2 ] The internal angles of a regular , flat hexagon are 120°, while the preferred angle between successive bonds in a carbon chain is about 109.5°, the tetrahedral ...
Since glucose is a basic necessity of many organisms, a correct understanding of its chemical makeup and structure contributed greatly to a general advancement in organic chemistry. This understanding occurred largely as a result of the investigations of Emil Fischer , a German chemist who received the 1902 Nobel Prize in Chemistry for his ...
Stereochemistry demands special attention because three-dimensionality is the most difficult part of a structure to visualize. Techniques for presenting 3-dimensional structures reflect the tastes of the artist. Three dimensionality is best highlighted by the depictions of bonds, using wedges, bolding, and hashed formats.
