Carbohydrate oxidases selectively oxidize glucose, galactose, and other sugars, accompanied by H₂O₂ production, oxygen consumption, or electron transfer. Different carbohydrate oxidases exhibit distinct substrate ranges and regioselectivities, acting on positions such as C1, C2, or C6 of the ...
The antioxidant enzyme defense system is an important barrier by which cells resist reactive oxygen species-induced damage. Superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GSH-Px/GPx) form a continuous reaction chain that removes superoxide anions, hydrogen peroxide, and ...
Amino acid oxidases are a class of flavin-dependent oxidoreductases that use molecular oxygen as the terminal electron acceptor to catalyze oxidative deamination of amino acids, generating the corresponding alpha-keto acids, ammonia (or ammonium), and hydrogen peroxide. This reaction system ...
