Synonymer & Information om | Engelska ordet LEVOROTATORY

Exempel på hur man kan använda LEVOROTATORY i en mening

• Louis Pasteur discovers that the racemic form of tartaric acid is a mixture of the levorotatory and dextrotatory forms, thus clarifying the nature of optical rotation and advancing the field of stereochemistry.
• Evidence from CD spectroscopy suggests left-handed helices are levorotatory and right-handed helices are dextrorotatory.
• After reacting aqueous racemic ammonium tartrate with a mold from Penicillium glaucum, he reisolated the remaining tartrate and found it was levorotatory.
• Rather, it indicates the compound's stereochemistry relative to that of the dextrorotatory or levorotatory enantiomer of glyceraldehyde.
• It differs from the natural nucleotide only with respect to the location of the sugar and base moieties, taking on an levorotatory configuration versus a dextrorotatory configuration as do the natural deoxynucleosides.
• Levoamphetamine is the levorotatory stereoisomer of the racemic amphetamine molecule, whereas dextroamphetamine is the dextrorotatory isomer.
• The dextrorotatory isomer corresponds to the S-configuration, and the levorotatory isomer to the R-configuration The data given at right is for the racemate.
• It is the levorotatory enantiomer of fenfluramine, the racemic form of the compound, whereas the dextrorotatory enantiomer is dexfenfluramine.
• The reaction of equilenin or dihydroequilenin with potassium hydroxide was also found to produce bisdehydrodoisynolic acid, whose levorotatory isomer is an estrogen with an "astonishingly" high degree of potency, while the dextrorotatory isomer is inactive.
