Starch phosphorylation
Webb15 jan. 2024 · Starch phosphate, which results from the addition of ester groups to the starch polymers, can be achieved by reacting starch with phosphorylation agents in the presence of an alkaline catalyst ( Chen et al., 2024). Webb2 maj 2024 · The phosphorylation and dephosphorylation of proteins can modulate the activities of proteins. Many phosphorylases are also involved in the synthesis of starch and sucrose, such as hexokinase and glucose-1-phosphate adenylyltransferase. Thus, the phosphorylation sites may be important for the synthesis of starch and polysaccharides.
