Reaction of galactose
WebGalactose-1-phosphate reacts with uridine diphosphate glucose (UDPGlc) to form UDP-galactose (UDP-Gal) and glucose-l-phosphate. In this reaction, catalyzed by galactose-1-phosphate uridyltransferase, galactose replaces glucose binding to UDP. Sign in to download full-size image 3. UDP-glucose formation. WebGalactose, for example, is phosphorylated in a manner analogous to step [1] of glycolysis. The reaction, catalyzed by a galactokinase, results in the formation of galactose 1 …

WebThe galactose oxidase-Schiff (GOS) reaction detects D-galactose-β-[1,3]-N-acetyl-D-galactosamine. This is a T-antigen expressed in mucus from malignant cells and colonic mucosa adjacent to cancer but not in normal mucosa. Previous studies using a qualitative GOS assay proved to be of limited value for the detection of colorectal neoplasia. WebSep 25, 2024 · This reaction is illustrated below for D-glucopyranose and methanol which forms a mixture of alpha and beta methyl-glucopyranosides. As is generally true for most acetals, glycoside formation involves the loss of an equivalent of water. The acetal product is stable to base and alkaline oxidants such as Tollen's reagent.
