Die Purinbiosynthese ist ein Stoffwechselweg, der die Biosynthese des Purinringsystems ermöglicht. 3. Synthesis of the purine ring de novo is required especially when DNA is replicated so that, although present in most tissues, the activity of the metabolic pathway is highly variable. De novo synthesis refers to the synthesis of complex molecules from simple molecules such as sugars or amino acids, as opposed to recycling after partial degradation.For example, nucleotides are not needed in the diet as they can be constructed from small precursor molecules such as formate and aspartate. De novo synthesis refers to the synthesis of complex molecules from simple molecules such as sugars or amino acids, as opposed to recycling after partial degradation.For example, nucleotides are not needed in the diet as they can be constructed from small precursor molecules such as formate and aspartate.
