asymmetric carbon

The 2-position is an asymmetric carbon, so there are two enantiomers of this compound.

They are configurated S at the remaining asymmetric carbon atom (see below).

Most compounds that contain one or more asymmetric carbon atoms show enantiomerism.

He developed the Fischer projection, a symbolic way of drawing asymmetric carbon atoms.

The aldotetroses have two chiral centers ("asymmetric carbon atoms") and so 4 different stereoisomers are possible.

Mefloquine is a chiral molecule with two asymmetric carbon centres, which means it has four different stereoisomers.

If a molecule contains a single asymmetric carbon atom or stereocenter, it will form two non-superimposable mirror images.

Because they have at least one asymmetric carbon center, aldoses with three or more carbon atoms exhibit stereoisomerism.

If a molecule contains two asymmetric carbons, there are up to 4 possible configurations, and they cannot all be non-superimposable mirror images of each other.

The naturally occurring compound is also chiral with 6 asymmetric carbon atoms including one quaternary one.

Helicenes are notable for having chirality while lacking both asymmetric carbons and chiral centers.

The 2,3-dimercaptosuccinic acid molecule has two stereocentres (two asymmetric carbons), and can exist as three different stereoisomers.

All amino acids except glycine (the simplest one) are optically active, having an asymmetric carbon atom.

The feature that is most often the cause of chirality in molecules is the presence of an asymmetric carbon atom.

The R conformation of the asymmetric carbon atom seems to be essential for GR affinity.

There are a few known compounds that do have asymmetric carbons, but, being non-dissymetric with respect to the whole molecule, do not show enantiomerism.

Thus, meso tartaric acid has two asymmetric carbons but is still optically inactive because they are equal and opposite to each other.

Racemases catalyze the stereochemical inversion around the asymmetric carbon atom in a substrate having only one center of asymmetry.

A chiral carbon or asymmetric carbon is a carbon atom which is asymmetric.

Dichlorprop possesses a single asymmetric carbon and is therefore a chiral molecule, however only the R-isomer is active as an herbicide.

Because the chemical transformations did not affect the asymmetric carbon atom, this sequence demonstrated that (-)-lactic acid was also a (R)-enantiomer.

Ondansetron is a racemate but the stereochemistry of the asymmetric carbon atom is not an important factor in the 5-HT receptor interaction.

The nitrogen bridge is between C-1 and C-5; there are two asymmetric carbons, but tropane is optically inactive due to symmetry.

Knowing the number of asymmetric carbon atoms, one can calculate the maximum possible number of stereoisomers for any given molecule as follows:

The asymmetric carbon atom is the one attached to two carbon atoms, an oxygen atom, and a hydrogen atom.
