What's the difference between raceme and racemose?
Raceme
Definition:
(n.) A flower cluster with an elongated axis and many one-flowered lateral pedicels, as in the currant and chokecherry.
Example Sentences:

(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.

(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.
(14) The vasodilating potency of d-alprenolol and d-propranolol was not significantly different from that of the respective racemic mixtures.
(15) High-pressure liquid chromatographic (HPLC) methods have been developed for the determination of drug content, racemate A and related compounds in nadolol raw materials.
(16) The effects of the d- and l-isomers of pentazocine were compared to that of racemic pentazocine on contractions of the mouse isolated vas deferens.
(17) Our results indicate that racemic EM 12 as well as its enantiomers are chemically and metabolically more stable than thalidomide; however, extensive racemisation occurs both in vivo and in vitro.
(18) These data, coupled with the equilibrium fractionation factor for the 2-position of proline (which has been determined to be 1.17), provide the transition-state factors for each of the in-flight protons, and delineate the nature of the transition state(s) for the enzyme-catalyzed racemization.
(19) Consequently, racemic compounds showed approximately half potency of the corresponding enantiomers.
(20) S(+)-ibuprofen and R(-)-ibuprofen given alone more rapidly reached significantly higher maximal plasma concentrations than after the same doses of the racemic compound.
Racemose
Definition:
(a.) Resembling a raceme; growing in the form of a raceme; as, (Bot.) racemose berries or flowers; (Anat.) the racemose glands, in which the ducts are branched and clustered like a raceme.
Example Sentences:
(1) Five patients had parenchymal cysts and presented with epilepsy; three had the racemose form and presented with hydrocephalus.
(2) We have reported a case of a racemose cyst of the fourth ventricle.
(3) Congenital anastomoses can be of the racemose hemangioma type, with severe malformation of the retinal vessels, ocular complications, and neurologic manifestations, or as simple A-V shunts with visual impairment but limited tendency to show other ocular or neurologic involvement.
(4) Microscopic examination showed the racemosal type of cysticercus but no scolex was found.
(5) The coenuri closely resembled examples of racemose cysticerci described in the literature and the present results are discussed with reference to human cases of asexually proliferating larval cestode infections.
(6) Clinical progression requires surgery, especially for racemose angiectasia.
(7) A thin subependymal or subpial rim of high signal intensity around the intraventricular and one of the racemose cysts was consistent with tissue reaction and aided diagnosis.
(8) Bronchoscopic examination revealed a polypoid tumor of the left B4 bronchus, which was resected and diagnosed as racemose hemangioma.
(9) Five patients with either capillary-cavernous hemangiomas or arteriovenous racemose hemangiomas were selected to illustrate the angiographic features of vascular malformations of the face as well as problems in angiographic evaluation and therapeutic techniques.
(10) A histological examination of a piece of the reddish, racemose tumor removed during microlaryngoscopy revealed only some slight nonspecific inflammatory changes.
(11) As well, they demonstrate that repeated cerebrospinal fluid analysis may result in diagnostic confirmation of intracerebral cysticercosis of the racemose type.
(12) generalized racemose livedo and recurrent cerebrovascular disease, is presented.
(13) Although necessary for shaping a normal racemose inflorescence, the squa function is not absolutely essential for flower development.
(14) Both patients with arteriovenous malformation had dilated, racemose feeding arteries and early dense filling of the draining veins.
(15) Fluid in apparently live cysticerci and in racemose cysts had MR signal properties closely paralleling CSF.
(16) Ultrathin serial sectioning and labeling with tannic acid have demonstrated that most plasmalemmal vesicles of rat vascular endothelial cells are not free, but rather are conjoined in three dimensions to form racemose invaginations from the cell surfaces.
(17) This syndrome is characterized by the association between generalized racemose livedo and disorders of the central nervous system, predominantly being present as cerebrovascular lesions and seizures.
