Glyoxal is a chemical compound made of carbon, hydrogen, and oxygen. It has the chemical formula C 2 H 2 O 2 or (CHO) 2. It is the simplest dicarbonyl, a type of chemical that has two C=O double bonds near each other. Glyoxal reacts with starch and cellulose to form cross-links.

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 of using glyoxal instead of formaldehyde ( Mattioda et al ...

Dec 15, 2020 · Whereas formalin is buffered near neutral pH of 7, glyoxal functions best at a lower pH between 4 and 5. The low pH causes red blood cells (RBCs) to lyse and changes the affinity of eosin to tissue elements. Eosin is typically attracted to the alkaline components in tissue, but because glyoxal is acidic, tissue basophilia is reduced.

Jan 29, 2024 · Glyoxal is a highly reactive aldehyde widely present in common diet and environment and inevitably generated through various metabolic pathways in vivo. Glyoxal is easily produced in diets high in carbohydrates and fats via the Maillard reaction, carbohydrate autoxidation, and lipid peroxidation, etc.
