It is levorotatory or dextrorotatory according to the temperature and concentration.

The levorotatory (L) form may antagonize the effects of the dextrorotatory isomer.

Fructose is even more strongly levorotatory than glucose is dextrorotatory.

An R isomer can be either dextrorotatory or levorotatory, depending on its exact substituents.

Levoamphetamine is the levorotatory stereoisomer of the amphetamine molecule.

The levorotatory form, called levomethamphetamine, is an over-the-counter drug used in inhalers for nasal decongestion.

"At the molecular level, it would appear to be a levorotatory form of the Gnawing bacillus," Selar began.

Chemically, it is a hormonally active levorotatory enantiomer of the racemic mixture norgestrel.

Santonin is optically levorotatory.

Consequently, the L in PLP does not indicate a levorotatory chiral center.

The two stereoisomers of tetramisole were subsequently synthesized, and the levorotatory isomer was given the name levamisole.

A negative value means levorotatory rotation and a positive value means dextrorotatory rotation.

It is not possible to determine whether a given chiral molecule will be levorotatory or dextrorotatory directly from its configuration, except via detailed computer modeling.

The dextrorotatory d-isomer corresponds to the S-configuration, and the levorotatory l-isomer to the R-configuration.

It is a sour white crystalline substance, consisting of a combination of dextrorotatory and levorotatory tartaric acids.

The maleic acid acid salt of the Levorotatory isomer is sold as the prescription drug Rotoxamine.

Levorotatory protein forms, common on almost every "nonseeded" planet, were almost completely absent in the ch'Rihan/ch'Havran biosystems.

The N-methylphenylethanolamine isolated from Halostachys caspica, and given the alkaloid name "halostachine", was found to be the levorotatory enantiomer:

It is the levorotatory enantiomer of fenfluramine, the racemic form of the compound, whereas the dextrorotatory enantiomer is dexfenfluramine.

A compound with dextrorotation is called dextrorotatory or dextrorotary, while a compound with levorotation is called levorotatory or levorotary.

After reacting aqueous racemic ammonium tartrate with a mold from Penicillium glaucum, he reisolated the remaining tartrate and found it was levorotatory.

The effect is due to the chirality of the molecules, and indeed the mirror-image isomer, -glucose, is levorotatory (rotates polarized light counterclockwise) by the same amount.

The fact that -glucose is dextrorotatory is a combined effect of its four chiral centers, not just of C-2; and indeed some of the other -aldohexoses are levorotatory.

The dextrorotatory isomer corresponds to the S-configuration, and the levorotatory isomer to the R-configuration The data given in the Chembox, at right, is for the racemate.

It is the levorotatory stereoisomer of the synthetic morphinan (Dromoran) and a pure opioid agonist, first described in Germany in 1948 as an orally active morphine-like analgesic.
