Adenosine 3'-phosphate 5'-phosphosulfate, tetralithium salt

3′-Phosphoadenosine 5′-phosphosulfate tetralithium salt (PAPS tetralithium salt) is the cosubstrate and the source of sulfonic acid groups in sulfation reactions. 3′-Phosphoadenosine 5′-phosphosulfate tetralithium salt is important for maintaining sulfation balance in living organisms[1].

Prepared enzymatically. A substrate for sulfotransferases, including Sulfotransferase, Nod Factor (Cat. No. 574300).
