A monosaccharide derivative normally gives rise to a dialdehyde, a disaccharide derivative to two dialdehyde units linked together, and a polysaccharide gives a dialdehyde polymer. The same aldehydic products may be obtained by oxidation with lead tetraacetate. Dialdehyde methanolate defines the group ...
Periodate oxidation of 1,2-O-cyclohexylidenemyoinositol gives cis-3,4-cyclohexylidenedioxy-2,5-dihydroxytetrahydrofuran (III), a compound which liberates meso-tartraldehyde on mild acid hydrolysis. Condensation with nitromethane provides... SJ Angyal,SD Gero - 《Australian Journal of Chemistry》 被...
IV – Asymmetric Oxidation Reduction, C–N A. Yanagisawa in Comprehensive Chirality, 2012 5.4.3.5.3 amino acid-catalyzed α-aminoxylation Direct catalyticasymmetric α-aminoxylation has been first reported by Zhong using aliphatic aldehydes as the substrates and L-proline as the organocatalyst...

cerevisiae responds by detoxifying its environment through the conversion of the toxic phenolic compounds, using a series of decarboxylation and oxidation processes into less toxic derivatives which the cells can then effectively cope with. This work highlights the in situ detoxification mechanisms in S....
The metabolism of 4-HNE in hepatocytes has been reported to be dependent on three enzymatic pathways: oxidation with ALDH, reduction with alcohol dehy- drogenase, and conjugation with glutathione (Hartley et al. 1995). Recently, we found that ALDH2 deficiency in PC12 cells increased cell ...

Lipid droplet (LD) binding proteins in mammary glands and in adipocytes were previously compared and striking similar sets of these specific proteins demon
Fig. 2. Oxidation of guanine (Gua) and adenine (Ade) by OH, one-electron oxidants and singlet oxygen (1O2). The formation of 8-oxoGua and Fapy depends on the presence of reducing agents and oxygen. The reaction of 1O2 with Gua specifically gives 8-oxoGua. The yield of Ade oxidatio...
Glyoxal (OHC–CHO) is a dialdehyde that can be obtained from several natural sources, such as from the oxidation of lipids or as a by-product of biological processes (Hirayama et al., 1984). The low vapor tension of the glyoxal solution and its low toxicity are some of the advantages ...
