Food Carbohydrate Chemistry
Thus, being a D- or L-sugar does not predict whether a sugar is dextrorotary or
levorotary. The designation D and L should not be confused with d and l, which
denotes having optical activity that is dextrorotary or levorotary. (The trivial names

Latin), whereas in the opposite case the rotation will be counterclockwise (
levorotary, laevus: Latin). Mixtures of D- and L-isomers are called racemic
mixtures. The specific rotary power of a specimen is defined as the angle of
rotation with ...
Robert Splinter, Brett A. Hooper, 2006
Every organism on Earth has a metabolism that is limited to using dextrorotatory
carbohydrates and levorotary amino acids. The other form can be toxic or lethal if
taken in large amounts. Enantiomer forms differ in their biological activity in the ...

Chestnut's Obstetric Anesthesia: Principles and Practice
The direction inwhichthe isomers rotate polarized light distinguishes them as
either dextrorotary (D) or levorotary(L) isomers. This distinction is important,
because individual isomers of thesamedrug may havedifferent biologic effects.
Asarule ...

G Protein-coupled Receptors: Molecular Pharmacology
Moreover, in agreement with the known stereoselectivity of β-adrenergic
receptors for antagonists such as propranolol and agonists such as adrenaline,
the dextrorotary isomers display lower affinity than the levorotary isomers. In this
respect ...
Georges Vauquelin, Bengt von Mentzer, 2008
Thus, the amino acids of all living forms are levorotary, that is, lefthanded.
Righthanded molecular forms areonly found inDNA and RNA; all the other
components of living beingsare built from lefthanded amino acids, other than a
couple of ...
1989) than the levorotary form, so that the half-life of S-(+)-MDMA is 73.8 to 210
min while the half-life of R-(—)-MDMA is 100.7 to 350 min (Fallon et al. 1999,
Verebey et al. 1988, Pacifici et al. 2001). The mean plasma concentration of the ...

Basic Principles of Forensic Chemistry
One enantiomer will rotate light clockwise (right) and is said to be dextrorotary (or
also dextrorotatory), whereas the other will rotate light counterclockwise (left) and
is referred to as levorotary (or also levorotatory). The direction of rotation is ...

Evolution: Principles and Processes
Molecules either deflect light to the left (are levorotary) or to the right (are
dextrorotary). A mixture of equal forms averages out the optical activity and the
molecule exhibits no chirality. The amino acids in carbonaceous chondrites
possess both ...

Pharmaceutical Chemistry
the levorotary form of the drug is the only active form; (2) two phenyl groups
represent an important component of the activity; (3) meta substituents on the
aromatic ring will increase the activity while ortho substituents exhibit steric
hindrance for ...

If the light is rotated anticlockwise they are known as levorotary (l) or (-). Another way of denoting an enantiomer is using the configuration of ... «Chromatography Today, Sep 14»
