Which molecule does NOT require 5-phosphoribosyl-1-pyrophosphate (PRPP) as a substrate for biosynthesis?

Question

Quizplus · Accepted Answer

All of these molecules require 5-phosphoribosyl-1-pyrophosphate (PRPP) for their biosynthesis. PRPP is a key substrate in the synthesis of purine nucleotides (such as adenosine monophosphate and guanosine monophosphate), pyrimidine nucleotides (such as cytidine monophosphate), and certain amino acids like histidine.
