What's the difference between aldehyde and lophine?
Aldehyde
Definition:
(n.) A colorless, mobile, and very volatile liquid obtained from alcohol by certain processes of oxidation.
Example Sentences:
(1) The compounds 1-3 in reaction with nicotine aldehyde or p-chlorobenzaldehyde were transformed into appropriate anilides of 2,3-epoxypropionic acid 4-9.
(2) The effects of inhibitors of aldehyde dehydrogenase activity on the sensitivity of murine pluripotent hematopoietic stem cells to oxazaphosphorine anticancer agents, e.g.
(3) With cortisol and cortisol-21-aldehyde, product inhibition patterns showed only slope effects with steroid product and NAD+, suggesting a "random" mechanism.
(4) At alkaline pH, the Schiff's base equilibrium can be continuously and specifically displaced by reduction in situ with sodium cyanohydridoborate, which on the other hand leaves intact the reacting aldehyde groups of oxidized tRNA.
(5) At low (1-2 microM) concentrations of the drug, the oxidative demethylation of lanosterol was inhibited by about 70% in the subcellular fractions but there was no effect on the metabolism of the 3 beta, 32-diol or the 32-aldehyde.
(6) In the scope of our research about the antimicrobial activity of aldehyde-amin-condensates a number of partly new unsymmetrically substituted animals was synthesized by reaction of formaldehyde with different secondary amines.
(7) Certain mouse and human hematopoietic progenitor cells also contain an aldehyde dehydrogenase that catalyzes the detoxification of aldophosphamide, but the specific identity of this enzyme remains to be established.
(8) A simple method for distinction between RNA- and DNA-containing structures in aldehyde- and osmiumtextroxide-fixed electron microscopic autoradiographs (or ordinary thin sections) is described: the developer and the acetic acid used for processing autoradiographs extract selectively uranium acetate from DNA containing-structures which, after staining with lead citrate, leads to a characteristically 'bleached' appearance of the DNA.
(9) One was identified as viridomycin A, the ferrous chelate of 4-hydroxy-3-nitrosobenzaldehyde; the second (actinoviridin A) was the corresponding carboxylic acid chelate and the third (viridomycin E) was a hybrid chelate containing both the aldehyde and acid ligands.
(10) Microfluorometric method has been described for the determination of aldose reductase and aldehyde reductase II activities in human erythrocyte, brain, and lens.
(11) The aldehyde is strongly bound in the active site along the entire length of the alkyl chain with the strongest interaction at the CHO group.
(12) These localizations correspond best to the clear areas found in aldehyde-fixed tissue.
(13) The differences between periodate- and NAGO-induced aldehydes were demonstrated by flow cytometry of cells stained with a novel fluoresceinated hydrazide and by an electrophoretic procedure performed with biocytin hydrazide and 125I-streptavidin.
(14) Major fatty aldehydes of the phosphatidylethanolamine were 14:0 (62%), unidentified long chain forms (24%), 16:0 (7%), 18:0 (4%), 18:1 (3%).
(15) The symmetrical reagent 5,5'-dithiobis-(1-methyltetrazole) activates mitochondrial aldehyde dehydrogenase approximately 4-fold, whereas the smaller related compound methyl l-methyltetrazol-5-yl disulphide is a potent inactivator.
(16) Microwave fixation in dilute aldehyde solution has been reported to be superior to fixation in formaldehyde for the preservation of antigens.
(17) Clofibrate treatment caused a 1.5 to 2.3-fold increase in the liver specific aldehyde dehydrogenase activity.
(18) In addition, there are basic differences in the PNI formation on aldehyde-treated pericardium and natural aortic valves as compared to the Dacron fabric.
(19) The oxazolidine molecules were synthesized through the condensation of ephedrine and ephedrine-related molecules with aromatic aldehydes.
(20) The particles stain adequately with lead after aldehyde-OsO(4) fixation in phosphate buffer and provide a relatively wide set of probes ( approximately 45 A-300 A) for work on the large and small pore systems.
Lophine
Definition:
(n.) A nitrogenous organic base obtained by the oxidation of amarine, and regarded as a derivative of benzoic aldehyde. It is obtained in long white crystalline tufts, -- whence its name.
