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 synthesis of the mixed Thr(P), Tyr(P)-containing peptide, Ala-Thr(P)-Tyr(P)-Ser-Ala, was accomplished by “phosphite-triester” phosphorylation of the resin-bound Thr Tyr-containing peptide using di-t-butyl N,N-diethylphosphoramidite as the phosphitylation reagent. darter group discount code
