Phosphorylation of sugars is often the first stage in their catabolism. Phosphorylation allows cells to accumulate sugars because the phosphate group prevents the molecules from diffusing back across their transporter. Phosphorylation of glucose is a key reaction in sugar metabolism. The chemical equation for the conversion of D-glucose to D-glucose-6-phosphate in the first step of glycolysis is given by: WebThe Art of Phosphitylation. The preparation of new biologically active entities has generated immense study in the field of phosphorylation, specifically with oligonucleotides, modified …
