Roles Classification
Chemical Role(s): Bronsted base
A molecular entity capable of accepting a hydron from a donor (Bronsted acid).
(via organic amino compound )
Bronsted acid
A molecular entity capable of donating a hydron to an acceptor (Bronsted base).
(via oxoacid )
Biological Role(s): antimetabolite
A substance which is structurally similar to a metabolite but which competes with it or replaces it, and so prevents or reduces its normal utilization.
carcinogenic agent
A role played by a chemical compound which is known to induce a process of carcinogenesis by corrupting normal cellular pathways, leading to the acquistion of tumoral capabilities.
