Resolution

1. High performance liquid chromatography methods also offer the possibility of using chiral solvents or additives to achieve resolution of enantiomers. (Web site)

Structural Isomers

1. Three types of isomers are structural isomers, geometric isomers, and enantiomers.

Mixture

1. Optically active tertiary haloalkanes produce a mixture of two enantiomers (mirror image isomers). (Web site)
2. A mixture of equal amounts of both enantiomers is said to be a racemic mixture. (Web site)

Compound

1. Enzymes however can distinguish between different enantiomers of a compound, and organisms often prefer one isomer over the other.

Compounds

1. Compounds (1a), (1b) and (1c) each has enantiomers based on its asymmetric carbon atom.

Amino

1. GC-MS analysis of diaminopimelic acid stereoisomers and amino acid enantiomers in rumen bacteria. (Web site)
2. Thus, chemical and physical methods have been sought to prepare or separate the individual enantiomers of an amino acid or amine. (Web site)

Warfarin

1. Warfarin is a mixture of enantiomers having different intrinsic activities at the vitamin K epoxide reductase (VKER) enzyme. (Web site)

Pharmacokinetics

1. Pharmacokinetics and pharmacodynamics of the enantiomers of warfarin in man. (Web site)

Tartaric

1. Racemic acid is the racemic form of tartaric acid forming a mixture of two enantiomorphic crystals each form consisting of one of the two enantiomers. (Web site)

Molecule

1. Normally, the two enantiomers of a molecule behave identically to each other.
2. Glyceraldehyde contains a chiral carbon, and therefore, there are two enantiomers of this molecule.

Panthenol

1. Panthenol comes in two enantiomers, D and L. Only D -panthenol (dexpanthenol) is biologically active, however both forms have moisturizing properties.

Snub Cube

1. Compound of two snub cubes - This uniform polyhedron compound is a composition of the 2 enantiomers of the snub cube.

Chiral

1. Two chiral enantiomers exist for monosodium glutamate, but only the naturally occurring L -glutamate form is used as a flavour enhancer.
2. When they react with another molecule THAT IS CHIRAL the reaction rates are NOT the same for the two enantiomers.
3. Different enantiomers of the same chiral drug can have very different pharmological effects, mainly because the proteins they bind to are also chiral. (Web site)

Enantiomer

1. They can also be separated from racemic mixtures of enantiomers by complexing one enantiomer with a chiral molecule. (Web site)
2. For example, in the case of glutamic acid, one of the enantiomers (L-form) has flavor while the other enantiomer (D-form) has no flavor. (Web site)

Diastereomers

1. Dextrorotatory - Diastereomers - Two or more isomers of a molecule which are not enantiomers of one another. (Web site)
2. The Aminopurine Compounds can have chiral centers and can occur as racemates, individual enantiomers or diastereomers, and mixtures thereof. (Web site)

Mirror Images

1. However, the isomers are not mirror images of one another, so they are not enantiomers; therefore they must be diastereomers. (Web site)

Stereoisomers

1. Such isomers include, e.g., stereoisomers, e.g., chiral compounds, e.g., diastereomers and enantiomers. (Web site)
2. It exists as a pair of mirror image stereoisomers (enantiomers), but only the naturally occurring L -glutamate form is used as a flavour enhancer.
3. Diels-Alder reactions can lead to formation of a variety of structural isomers and stereoisomers (enantiomers and diastereomers).

Optical Isomers

1. Optical isomers, also know as chiral molecules or enantiomers, exhibit this optical activity in varying degrees. (Web site)
2. Optical isomers or enantiomers are stereoisomers which exhibit chirality. (Web site)
3. For example, one of the optical isomers (enantiomers) of the amino acid alanine is known as (+)alanine. (Web site)

Enantiomers

1. There are many different classes of isomers, like stereoisomers, enantiomers, geometrical isomers, et cetera (see chart below). (Web site)
2. Two mirror images of a chiral molecule are called enantiomers or optical isomers.
3. Two mirror images of a molecule that cannot be superimposed onto each other are referred to as enantiomers or optical isomers. (Web site)
