Glyoxal

International Journal of Toxicology, 2023
The Expert Panel for Cosmetic Ingredient Safety reviewed information that has become available since their year 2000 assessment, along with updated information regarding product types, and frequency and concentrations of use, and reaffirmed their original conclusion that Glyoxal is safe for use in products intended to be applied to the nail at ...

Synthesis of glyoxalic acid from glyoxal

Process Biochemistry, 2000
Abstract A chemo-enzymic route was devised for the synthesis of glyoxalic acid from glyoxal. Glyoxal was converted chemically to glycolic acid, which was oxidised to glyoxalic acid with a glycolate oxidase from spinach. The two steps were studied independently as well as singly. The conversion of glyoxal to glycolic acid was 95% at a mol ratio of 1:1.

Reaction of glyoxal and glyoxal/glycol with wood

Wood Science and Technology, 1993
In terms of the problem of formaldehyde-releasing, glyoxal is one of the interesting dialdehydes as a crosslinking agent for wood. In the present report, the reaction of glyoxal and glyoxal/glycol with the wood of Japanese ash (Fraxinus mandshurica Rupr. var. japonica Maxim.) has been studied. Particular attention to the structure of the product (after

Trapping of glyoxal by propyl, octyl and dodecyl gallates and their mono-glyoxal adducts

Food Chemistry, 2018
Glyoxal (GO) is one of the major toxic intermediates generated during lipid oxidation and degradation. We investigated the inhibitory activities and mechanisms of propyl, octyl, and dodecyl gallates (PG, OG, and DG) on the formation of GO in buffer and during thermo-processing of corn oil, and the anti-carbonyl and antioxidative activities of the mono ...

Microwave spectra of cis-glyoxal-d1 and cis-glyoxal-d2

Journal of Molecular Spectroscopy, 1976
Abstract The microwave spectra of cis-glyoxal-d1 (C2HDO2) and cis-glyoxal-d2 (C2D2O2) have been obtained and assigned in the range from 18 to 40 GHz. The determined rotational constants for C2HDO2 were: A = 23857.40 ± 0.36, B = 6075.89 ± 0.09, and C = 4849.65 MHz; and for C2D2O2, A = 21521.82 ± 0.21, B = 5968.99 ± 0.04, and C = 4680.61 ± 0.05 MHz.

Flavour chemistry of methylglyoxal and glyoxal

Chemical Society Reviews, 2012
Methylglyoxal (MGO) and glyoxal (GO), known as reactive carbonyl species, can be generated endogenously and exogenously (human body and food system). They are attracting increased attention because of their relationship with diabetes and flavour generation. In this review, their characteristics relating to flavour chemistry are discussed.

Ab initio studies of the 3nπ* states of glyoxal and methyl glyoxal

Chemical Physics Letters, 1978
Abstract Results of ab initio calculations on the 3nπ* states of glyoxal and methyl glyoxal are reported. The symmetry unconstrained ΔESCF transition energies, unlike the symmetry constrained results, are found to be very similar. These calculations explain some anomalies which have appeared in the literature recently.

Influence of glyoxal on cell function

Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1968
Abstract Glyoxal down to 0.5 mM is cytotoxic for human fibroblasts in culture by blocking DNA and protein synthesis primarily. The synthesis of rapidly-labelled RNA is not inhibited by short treatment even with high doses of glyoxal; that of ribosomal RNA is suppressed almost entirely after a 5-h treatment, but no change was observed in the ...

Denaturation and Electrophoresis of RNA with Glyoxal

Cold Spring Harbor Protocols, 2015
This protocol is used to denature and separate large mRNA molecules (0.5–10 kb) on agarose gels by electrophoretic size fractionation. Glyoxal (also called diformyl or ethanedial), the agent responsible for maintaining denaturation in this protocol, contains two carbonyl groups that react to form a cyclic ring structure with the imino and amino groups ...
