What's the difference between dissociate and dissociation?

Dissociate


Definition:

  • (v. t.) To separate from fellowship or union; to disunite; to disjoin; as, to dissociate the particles of a concrete substance.

Example Sentences:

  • (1) These results show that the pathogenic phenotypes of MCF viruses are dissociable from the thymotropic phenotype and depend, at least in part, upon the enhancer sequences.
  • (2) Structure assignment of the isomeric immonium ions 5 and 6, generated via FAB from N-isobutyl glycine and N-methyl valine, can be achieved by their collision induced dissociation characteristics.
  • (3) It has recently been suggested that procaine penicillin existed in solution in vitro and in vivo as a "procaine - penicillin" complex rather than as dissociated ions.
  • (4) Elongation of existing RNA primers by the human polymerase-primase was semi-processive; following primer binding the DNA polymerase continuously incorporated 20 to 50 nucleotides, then it dissociated from the template DNA.
  • (5) Blood gas variables produced from a computed in vivo oxygen dissociation curve, PaeO2, P95 and C(a-x)O2, were introduced in the University Hospital of Wales in 1986.
  • (6) The data shows a dissociation between ferritin synthesis, cellular accumulation and secretion for which the mechanisms have still to be elucidated.
  • (7) Electromechanic dissociation, sinus bradycardia, nodal rhythm followed by idioventricular rhythm and asystole, were observed following myocardial rupture.
  • (8) Transcription studies in vitro on repression of the tryptophan operon of Escherichia coli show that partially purified trp repressor binds specifically to DNA containing the trp operator with a repressor-operator dissociation constant of about 0.2 nM in 0.12 M salt at 37 degrees , a value consistent with the extent of trp operon regulation in vivo.
  • (9) These differences in central connectivity mirror the reports on behavioral dissociation of the facial and vagal gustatory systems.
  • (10) In contrast, the enzymic domain of the colicin (T2) remained in the aqueous phase and was recovered in a highly active form as a consequence of its dissociation from the immunity protein.
  • (11) Predominantly observed defects included neural crest cells in ectopic locations, both within and external to the neural tube, and mildly deformed neural tubes containing some dissociating cells.
  • (12) Inhibition assays indicate an apparent dissociation constant (Kd) corresponding to 4 x 10(-9) M and an affinity constant (Ka) to 2.5 x 10(8)M-1 to K562 erythroleukemia cells.
  • (13) When CO was photolytically dissociated from the reduced protein two recombination processes were observed with rates almost identical with those observed in the stopped-flow experiments (k+1 = 3.3 X 10(3)M-1-S-1 and k+2 = 6.0 X 10(2)M-1-S-1).
  • (14) On the other hand, ultraviolet (320-nm) light, absorbed by 3-hydroxy-pyridinium cross-links which were rapidly photolyzed, partially dissociated polymeric collagen aggregates from bovine Achilles tendon after subsequent heating.
  • (15) The corresponding dissociation constants range from 2.8 nM for the native enzyme and 8.5 nM for the 96K fragment to approximately 15 nM for the 68K and 90K fragments [0.20 N KCl, 50 mM 3-(N-morpholino)propanesulfonic acid, and 1 mM CaCl2, pH 7.3, 25 degrees C].
  • (16) Addition of pyridoxal 5'-phosphate to slow dissociating, high affinity 5S R[3H]E2 dimers free in cytosol induced rapid [3H]E2 dissociation, although the receptor remained unaltered in the transformed dimerized state.
  • (17) If VF persisted or if countershock resulted in asystole or a nonperfusing rhythm (electrical-mechanical dissociation [EMD]), the alternate drug (naloxone or epinephrine) was then given.
  • (18) Addition of albumin or GTP to the incubation medium enhanced the specific binding of PGE2 by decreasing the dissociation constant of the low affinity-high capacity binding sites.
  • (19) Dissociated cerebral hemisphere cells from 4- to 7-day-old chick embryos were cultured either on a collagen or a polylysine substrate in a serum-containing medium.
  • (20) Incubation of the enzyme-inhibitor complex with the sulfhydryl reagent caused dissociation into active ribonuclease and inactive inhibitor.

Dissociation


Definition:

  • (n.) The act of dissociating or disuniting; a state of separation; disunion.
  • (n.) The process by which a compound body breaks up into simpler constituents; -- said particularly of the action of heat on gaseous or volatile substances; as, the dissociation of the sulphur molecules; the dissociation of ammonium chloride into hydrochloric acid and ammonia.
