What's the difference between homologation and reaction?
Homologation
Definition:
(n.) Confirmation or ratification (as of something otherwise null and void), by a court or a grantor.

(20) The most striking homology was to yeast SEC7 in the central domain of the gene (57% identical over 466 bp) and also the protein level (42% identical amino acids; 39% conserved amino acids).
Reaction
Definition:
(n.) Any action in resisting other action or force; counter tendency; movement in a contrary direction; reverse action.
(n.) The mutual or reciprocal action of chemical agents upon each other, or the action upon such chemical agents of some form of energy, as heat, light, or electricity, resulting in a chemical change in one or more of these agents, with the production of new compounds or the manifestation of distinctive characters. See Blowpipe reaction, Flame reaction, under Blowpipe, and Flame.
(n.) An action induced by vital resistance to some other action; depression or exhaustion of vital force consequent on overexertion or overstimulation; heightened activity and overaction succeeding depression or shock.
(n.) The force which a body subjected to the action of a force from another body exerts upon the latter body in the opposite direction.
(n.) Backward tendency or movement after revolution, reform, or great progress in any direction.
Example Sentences:
(1) A 2.5-month-old child with cyanotic heart disease who required long-term PGE1 infusions; developed widespread periosteal reactions during the course of therapy.
(2) We used the polymerase chain reaction (PCR) to amplify the breakpoint area of alpha-thalassemia-1 of Southeast Asia type and several parts of the alpha-globin gene cluster to make a differential diagnosis between alpha-thalassemia-1 and Hb Bart's hydrops fetalis.
(3) The assembly reaction is accompanied by characteristic changes in fluorescence emission and dichroic absorption.
(4) Cantact placing reaction times were measured in cats which were either restrained in a hammock or supported in a conventional way.
(5) The effects of sessions, individual characteristics, group behavior, sedative medications, and pharmacological anticipation, on simple visual and auditory reaction time were evaluated with a randomized block design.
(6) If the method was taken into routine use in a diagnostic laboratory, the persistence of reverse passive haemagglutination reactions would enable grouping results to be checked for quality control purposes.
(7) Because cystine in medium was converted rapidly to cysteine and cysteinyl-NAC in the presence of NAC and given that cysteine has a higher affinity for uptake by EC than cystine, we conclude that the enhanced uptake of radioactivity was in the form of cysteine and at least part of the stimulatory effect of NAC on EC glutathione was due to a formation of cysteine by a mixed disulfide reaction of NAC with cystine similar to that previously reported for Chinese hamster ovarian cells (R. D. Issels et al.
(8) Between 22 HLA-identical siblings and 16 two-haplotype different siblings, a significant difference in concordance of reactions for the B-cell groups was noted.
