The key component is called 1-octen-2-one, which smells fungal-metallic even when highly diluted. The precursors to the odor molecules are lipid peroxides, which are produced when oils on skin are oxidized by certain enzymes or other processes (e.g. under UV light).
For centuries, humans have been perplexed by the musty metallic odor associated with handling iron objects or rubbing away a drop of blood from a cut. Also perplexing is the garlicky odor noticed by metallurgists when cast iron or steel rich in carbon and phosphorus is treated with an acid.
