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 )
Application(s): cross-linking reagent
A reagent with two reactive groups, usually at opposite ends of the molecule, that are capable of reacting with and thereby forming bridges between macromolecules, principally side chains of amino acids in proteins, allowing the locations of naturally reactive areas within the proteins to be identified.
A substance used as an indicator of a biological state.
