Statistics for asymmetric carbon atom.
The isoleucine and the threonine have one asymmetric carbon.
Having an asymmetric carbon atom.
One may initially be inclined to think this atom is not asymmetric because it is attached to two carbon atoms, but because those two carbon atoms are not attached to exactly the same things, there are two different groups of atoms that the carbon atom in question is attached to,therefore making it an asymmetric carbon atom.
They contain asymmetric carbon atoms.
The asymmetric carbon atom is the one attached to two carbon atoms, an oxygen atom, and a hydrogen atom.
They contain asymmetric carbon atoms.
An asymmetric carbon atom(chiral carbon) is a carbon atom that is attached to four different types of atoms or four different groups of atoms.
It has two asymmetric carbon atoms.
D-Erythrose D-Threose D-Erythrulose The aldotetroses have two chiral centers(asymmetric carbon atoms) and so 4 different stereoisomers are possible.
If n is the number of asymmetric carbon atoms then the maximum number of isomers= 2n(Le Bel-van't Hoff rule).
Except for glycine,the a-carbon atoms of other amino acids are asymmetric carbon atoms and therefore have optical activity.
There are three asymmetric carbon atoms in the tocopherol molecule located at the 2, 4′, and 8′ positions.
Most compounds that contain one or more asymmetric Carbon atoms show enantiomerism.
There are three asymmetric carbon atoms in the tocopherol molecule located at the 2', 4′, and 8′ positions.
Thus, meso tartaric acid has two asymmetric Carbons but is still optically inactive.
Knowing the number of asymmetric carbon atoms, one can calculate the maximum possible number of stereoisomers for any given molecule as follows: If n is the number of asymmetric carbon atoms then the maximum number of isomers= 2n(Le Bel-van't Hoff rule) As an example, malic acid has 4 carbon atoms but just one of them is asymmetric. .
The aldopentoses have three chiral centres("asymmetric carbon atoms") and so 8 different stereoisomers are possible.
The presence of an asymmetric carbon atom is one of several structural features that induce chirality in organic and inorganic molecules.
The aldotetroses have two chiralatrial centres("asymmetric carbon atoms") and so 4 different stereoisomers are possible.
Lenalidomide has an asymmetric carbon atom and can therefore exist as the optically active forms S(-) and R(+).
Most compounds that contain one or more asymmetric carbon(or other element) atoms show enantiomerism.
Vedaprofen contains an asymmetric carbon atom and, therefore, is a racemic mixture of a(+) enantiomer and a(-) enantiomer.
An aldopentose with 3 asymmetric carbon atoms has 23= 8 stereoisomers.
Knowing the number of asymmetric carbon atoms, one can calculate the maximum possible number of stereoisomers for any given molecule as follows.
A tetrose with 2 asymmetric carbon atoms has 22= 4 stereoisomers.
An aldohexose with 4 asymmetric carbon atoms has 24= 16 stereoisomers.
Optical isomerism is possible when an asymmetric carbon atom is present in the molecule(containing four different substituents).
Likewise, trans-cyclohexane- 1,4- dicarboxylic acid has asymmetric Carbons but also has a centre of symmetry(thereby making it a non-dissymmetric compound) and, therefore, exhibits no enantiomerism.
As an example, malic acid has 4 carbon atoms but just one of them is asymmetric.
