  2. Fischer projection - Wikipedia

    en.wikipedia.org/wiki/Fischer_projection

    The use of Fischer projections in non-carbohydrates is discouraged, as such drawings are ambiguous and easily confused with other types of drawing. The main purpose of Fischer projections is to show the chirality of a molecule and to distinguish between a pair of enantiomers. Some notable uses include drawing sugars and depicting isomers. [1]

  3. Structural formula - Wikipedia

    en.wikipedia.org/wiki/Structural_formula

    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. [1]

  4. Monosaccharide nomenclature - Wikipedia

    en.wikipedia.org/wiki/Monosaccharide_nomenclature

    The Fischer projection is a systematic way of drawing the skeletal formula of an open-chain monosaccharide so that each stereoisomer is uniquely identified. Two isomers whose molecules are mirror-images of each other are identified by prefixes ' D-' or ' L-', according to the handedness of the chiral carbon atom that is farthest from the carbonyl.

  5. Skeletal formula - Wikipedia

    en.wikipedia.org/wiki/Skeletal_formula

    The skeletal formula of the antidepressant drug escitalopram, featuring skeletal representations of heteroatoms, a triple bond, phenyl groups and stereochemistry. The skeletal formula, line-angle formula, bond-line formula or shorthand formula of an organic compound is a type of molecular structural formula that serves as a shorthand representation of a molecule's bonding and some details of ...

  6. Isomer - Wikipedia

    en.wikipedia.org/wiki/Isomer

    In chemistry, isomers are molecules or polyatomic ions with identical molecular formula – that is, the same number of atoms of each element – but distinct arrangements of atoms in space. [1] Isomerism refers to the existence or possibility of isomers.

  8. Structural isomer - Wikipedia

    en.wikipedia.org/wiki/Structural_isomer

    Functional isomers are structural isomers which have different functional groups, resulting in significantly different chemical and physical properties. [ 11 ] An example is the pair propanal H 3 C–CH 2 –C(=O)-H and acetone H 3 C–C(=O)–CH 3 : the first has a –C(=O)H functional group, which makes it an aldehyde , whereas the second has ...
