dextrorotary

Figures for both the racemic and the dextrorotary enantiomers are given:

It has a slightly sweet taste, is dextrorotary, and is much less soluble in water than either cane sugar or glucose.

Dextrorotary compounds have a positive specific rotation, while levorotary compounds have negative.

The first tissue samples had revealed that the Guest could conceivably digest dextrorotary sugars and proteins generally found in Earth life forms.

The drug that contains only dextrorotary methylphenidate is called d-TMP.

If a chiral molecule is dextrorotary, its enantiomer will be levorotary, and vice-versa.

A dextrorotary compound is often prefixed "(+)-" or "d-".

Metabolites of selegiline include L-amphetamine and L-methamphetamine (not to be confused with the more notorious and potent dextrorotary isomers).

A standard measure of the degree to which a compound is dextrorotary or levorotary is the quantity called the specific rotation [α].

The dextrorotary enantiomers are significantly more potent than the levorotary enantiomers, and some medications therefore only contain dexmethylphenidate.

Dextroamphetamine (the dextrorotary enantiomer) and levoamphetamine (the levorotary enantiomer) have different pharmacological properties.

The dextrorotary enantiomer of methadone, dextromethadone, is an NMDA antagonist rather than an opiate agonist.

The dextrorotary enantiomer of methylphenidate, known as dexmethylphenidate, is sold as a generic and under the brand names Focalin and Attenade.

It exists as two enantiomers: the levorotary form levamfetamine (INN) and dextrorotary form dexamfetamine (INN).

Methamphetamine occurs in two enantiomers, dextrorotary and levorotary; dextromethamphetamine possesses the well-known psychostimulant effects of the drug, while levomethamphetamine is CNS-inactive.

Anecdotally, the dextrorotary enantiomer is orally active in the 2 mg - 5 mg range as larger doses e.g. 25 mg+ would prove fatal, with a duration of 5-8 hours.

In some cases the (R)-enantiomer is the dextrorotary enantiomer, and in other cases the (R)-enantiomer is the levorotary enantiomer.

The dextrorotary form (d-methadone) acts as an NMDA antagonist and is devoid of opioid activity: it has been shown to produce analgesia in experimental models of chronic pain.

If there is a pair of enantiomers, each with one stereocenter, then one enantiomer is R and the other is S, and likewise one enantiomer is levorotary and the other is dextrorotary.

It is obtained by hydrolysis of cocaine with acids or alkalis, and crystallizes with one molecule of water, the crystals melting at 198-199 C. It is levorotary, and on warming with alkalis gives iso-ecgonine, which is dextrorotary.

The and convention for amino acid configuration refers not to the optical activity of the amino acid itself, but rather to the optical activity of the isomer of glyceraldehyde from which that amino acid can, in theory, be synthesized (-glyceraldehyde is dextrorotary; -glyceraldehyde is levorotatory).
