salvage pathway
Molecular reuse mechanism
A salvage pathway is a biochemical route that recycles partially degraded molecules rather than synthesizing them from scratch.
Cells use salvage pathways to recover nucleotides, amino acids, and other building blocks from broken-down DNA, RNA, or proteins: The salvage pathway allows cells to reuse purines efficiently.
These pathways conserve energy compared to de novo synthesis.
