- In stereochemistry, a
stereocenter of a
molecule is an atom (center), axis or
plane that is the
focus of stereoisomerism; that is, when
having at least...

stereogenic element is a
stereogenic center, or

organic compounds,
stereocenters most
frequently take the form of a
carbon atom...

mirror images of each other. When two
diastereoisomers differ from each
other at only one
stereocenter, they are epimers...
- the same, then
there is no
stereoisomer and the
double bond is not a
stereocenter, e.g. propene, CH3CH=CH2

- 3-aminopropanoic acid.
Unlike its
counterpart α-alanine, β-alanine has no
stereocenter. In
terms of its biosynthesis, it is
formed by the
degradation of dihydrouracil...
-
purpose of the CIP
system is to ****ign an R or S
descriptor to each
stereocenter and an E or Z
descriptor to each
double bond so that the configuration...
- a type of

chirality center is also
called a
chiral center or an
asymmetric center. Some

carbonyls adjacent to a pre-existing
stereocenter, then the new
stereocenters may form at a
