sec·on·dar·y me·tab·o·lite

a metabolite synthesized in a step in secondary metabolism.

secondary metabolite

a product of microbial cells in culture when growth is slowing down. While having no obvious role in the cellular physiology of the producer, secondary metabolites are sometimes most useful to humans, e.g. as antibiotics. Compare PRIMARY METABOLITE.
