Absolute configuration

An absolute configuration refers to the spatial arrangement of the atoms of a chiral molecular entity (or group) and its stereochemical description e.g. R or S, referring to Rectus, or Sinister, respectively.

Acetal

An acetal is a functional group with the following connectivity R2C(OR')2, where both R' groups are organic fragments.

Aldehyde

An aldehyde or alkanal is an organic compound containing a functional group with the structure −CHO, consisting of a carbonyl center (a carbon double-bonded to oxygen) with the carbon atom also bonded to hydrogen and to an R group, which is any generic alkyl or side chain.

Aldohexose

An aldohexose is a hexose with an aldehyde group on one end.

Anomeric effect

In organic chemistry, the anomeric effect or Edward-Lemieux effect is a stereoelectronic effect that describes the tendency of heteroatomic substituents adjacent to a heteroatom within a cyclohexane ring to prefer the axial orientation instead of the less hindered equatorial orientation that would be expected from steric considerations.

Cahn–Ingold–Prelog priority rules

The Cahn–Ingold–Prelog (CIP) sequence rules, named for organic chemists Robert Sidney Cahn, Christopher Kelk Ingold, and Vladimir Prelog — alternatively termed the CIP priority rules, system, or conventions — are a standard process used in organic chemistry to completely and unequivocally name a stereoisomer of a molecule.

Carbohydrate

A carbohydrate is a biomolecule consisting of carbon (C), hydrogen (H) and oxygen (O) atoms, usually with a hydrogen–oxygen atom ratio of 2:1 (as in water); in other words, with the empirical formula (where m may be different from n).

Cis–trans isomerism

Cis–trans isomerism, also known as geometric isomerism or configurational isomerism, is a term used in organic chemistry.

Epimer

In stereochemistry, an epimer is one of a pair of stereoisomers.

Hemiacetal

A hemiacetal or a hemiketal is a compound that results from the addition of an alcohol to an aldehyde or a ketone, respectively.

Hydrogen bond

A hydrogen bond is a partially electrostatic attraction between a hydrogen (H) which is bound to a more electronegative atom such as nitrogen (N), oxygen (O), or fluorine (F), and another adjacent atom bearing a lone pair of electrons.

Ketone

In chemistry, a ketone (alkanone) is an organic compound with the structure RC(.

Mannose

Mannose, packaged as the nutritional supplement "d-mannose", is a sugar monomer of the aldohexose series of carbohydrates.

Melting point

The melting point (or, rarely, liquefaction point) of a substance is the temperature at which it changes state from solid to liquid at atmospheric pressure.

New!!: Anomer and Melting point · See more »

Monosaccharide nomenclature

Monosaccharide nomenclature is a set of conventions used in chemistry to name the compounds known as monosaccharides or "simple sugars" — the basic structural units of carbohydrates, which cannot be hydrolysed into simpler units.

Mutarotation

Mutarotation is the change in the optical rotation because of the change in the equilibrium between two anomers, when the corresponding stereocenters interconvert.

Open-chain compound

In chemistry, an open-chain compound (also spelled as open chain compound) or acyclic compound (Greek prefix "α", without and "κύκλος", cycle) is a compound with a linear structure, rather than a cyclic one.

Optical rotation

Optical rotation or optical activity (sometimes referred to as rotary polarization) is the rotation of the plane of polarization of linearly polarized light as it travels through certain materials.

Polarimetry

Polarimetry is the measurement and interpretation of the polarization of transverse waves, most notably electromagnetic waves, such as radio or light waves.

Pyranose

Pyranose is a collective term for saccharides that have a chemical structure that includes a six-membered ring consisting of five carbon atoms and one oxygen atom.

Ratio

In mathematics, a ratio is a relationship between two numbers indicating how many times the first number contains the second.

Reducing sugar

A reducing sugar is any sugar that is capable of acting as a reducing agent because it has a free aldehyde group or a free ketone group.

Rotation around a fixed axis

Rotation around a fixed axis or about a fixed axis of revolution or motion with respect to a fixed axis of rotation is a special case of rotational motion.

Specific rotation

In chemistry, specific rotation is a property of a chiral chemical compound.

Stereochemistry

Stereochemistry, a subdiscipline of chemistry, involves the study of the relative spatial arrangement of atoms that form the structure of molecules and their manipulation.

New!!: Anomer and Stereochemistry · See more »

Stereoisomerism

In stereochemistry, stereoisomers are isomeric molecules that have the same molecular formula and sequence of bonded atoms (constitution), but differ in the three-dimensional orientations of their atoms in space.
