StrainBaker's yeast
DescriptionAdenosine 3',5'-diphosphate, also known as 3'-phosphoadenylate or PAP, 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. Adenosine 3',5'-diphosphate is a strong basic compound (based on its pKa). Adenosine 3',5'-diphosphate exists in all living species, ranging from bacteria to humans. sulfite and adenosine 3',5'-diphosphate can be biosynthesized from phosphoadenosine phosphosulfate; which is catalyzed by the enzyme 3'-phospho-adenylylsulfate reductase. In yeast, adenosine 3',5'-diphosphate is involved in the metabolic pathway called the sulfur metabolism pathway.
