Nucleotide Metabolism | Purine Biosynthesis 1: Up to IMP

The video tutorial explains the biosynthesis of inosine monophosphate (IMP), a key purine nucleotide. It covers the initial steps of purine synthesis, starting with ribose 5-phosphate from the pentose phosphate pathway, and the formation of PRPP. The tutorial details the assembly of the purine ring on the ribose, highlighting the role of various enzymes and the use of ATP. The process involves multiple steps, including the conversion of GAR to FGAM and the cyclization to form the complete purine ring. The video concludes with the potential pathways for IMP to form AMP and GMP.
