MetaCyc Metabolic Pathway Database

DMSP Degradation

Biological processes influence geochemical cycles. The main input of sulfur to the atmosphere is dimethyl sulfide, which is formed by microbial degradation of marine algae biomass.

Reaction Atom Mappings Indicate Atom Flow

The compounds in MetaCyc reactions are color labeled to make it easy to follow the atom flow. You can cause the atoms to be numbered to more clearly identify corresponding atoms in reactants and products.

So what killed this guy?

Twenty people were executed around Salem, MA for using witchcraft to afflict young girls. Were the victims bewitched, or could it be something they ate?
