DescriptionPhosphoadenosine phosphosulfate, also known as 3'-phospho-5'-adenylyl sulfate or PAPS, belongs to the class of organic compounds known as purine ribonucleoside 3',5'-bisphosphates. These are purine ribobucleotides with one phosphate group attached to 3' and 5' hydroxyl groups of the ribose moiety. Phosphoadenosine phosphosulfate is a strong basic compound (based on its pKa). Phosphoadenosine phosphosulfate exists in all living species, ranging from bacteria to humans.
