The de novo pathway refers to the synthesis of biomolecules from simple precursors rather than from existing molecules, allowing for the creation of nucleotides and other essential compounds. This process is crucial for the production of nucleotides, particularly in situations where cells need to generate new DNA and RNA, influencing cellular growth and division. It contrasts with salvage pathways, which recycle existing nucleotides, emphasizing the importance of both mechanisms in nucleotide metabolism.
