Preposition: from

intestine: However, there was no difference in the absorption rate of purines from the small intestine between the two species of animals.

Converse of object

• absorb: The response curve of PD excretion vs purine absorbed is linear.
• contain: The DNA contains purines which are broken down to uric acid in the blood.

Adjective modifier

• exogenous: When no exogenous purines is available, the loss has to be replaced all by de novo synthesis.
• microbial: In this example, the amount of microbial purines absorbed is therefore 4.79 mmol/d.

• nucleoside: The phosphorylation of purine nucleosides to form nucleotides by nucleoside kinase is an alternative pathway of purine salvage.
• derivative: The term " purine derivative " was also used for the first time.
• metabolism: Methotrexate which interferes with purine metabolism was introduced almost 50 years ago.
• analog: All six of the patient showed a response to treatment with this purine analog.
• absorption: It was not possible to define a clear response curve of PD excretion to purine absorption from that data set.
• uptake: Thus, without the data of total purine uptake ( background plus infused ), the results obtained were confounded.
