Raceme
Definition:
(n.) A flower cluster with an elongated axis and many one-flowered lateral pedicels, as in the currant and chokecherry.
Example Sentences:
(1) These results indicate that both racemic and L-baclofen inhibit trigeminal transmission in man, probably because they interfere with excitatory transmission through the interneurons of the lateral reticular formation.
(2) In contrast to the enantiomeric discrimination observed with racemic amine, the individual isomers were metabolized at approximately the same rate.
(3) Routine enantiomeric analyses were successfully carried out on samples taken from animals dosed orally with the racemic drugs, providing important data on the possible levels of exposure to individual enantiomers during toxicity testing.
(4) Racemic verapamil and the L- and D-isomer increased cellular vincristine accumulation to the same extent.
(5) By this method, about 5.0 mg of racemic HCZ could be resolved completely in one run.
(6) The racemization-suppressing effect of other compounds were also evaluated by employing one of these model couplings to be at best only limitedly effective.

(8) The assay is reliable to 0.1% racemate with a detection limit of approximately 100 pmol.
(9) The allene oxide also opens to a zwitterion, which undergoes charge delocalization to form a planar intermediate; this structure is the achiral precursor of the stable end product of pericyclic ring closure, viz., racemic cis-12-oxo-PDA.
(10) Decreasing the water concentration in the reaction medium by adding methanol at 0 degrees C drastically reduces the rate of racemization without affecting the rate of transamination.
(11) Racemization of aspartic acid in dentin protein during the human lifetime progresses with age.
(12) Five diammine-Pt(II) or Pt(IV) coordination compounds, namely cis-diammine-dichloro-platinum (II) "cis-DDP", transdihydroxy-cis-diammine-dichloro-platinum (IV) "trans-ODDP", and derived substitution products of lactic acid (racemates or L-forms) with diminished toxicity in comparison to cis-DDP have been tested against mouse leukemia P388, and partly on melanoma B16 for antineoplastic activity.
(13) The racemic drug has unusual pharmacokinetic properties because of its concentration-dependent binding to plasma proteins in the therapeutic plasma concentration range.
