In chemistry, a disulfide bond (Br.E. disulphide bond) is a covalent bond, usually derived by the coupling of two thiol groups. The linkage is also called an SS-bond or disulfide bridge. The overall connectivity is therefore R-S-S-R. The terminology is widely used in biochemistry. In formal terms, the connection is a persulfide, in analogy to its congener, peroxide (R-O-O-R), but this terminology is obscure and is no longer used (except in reference to R-S-S-H or H-S-S-H compounds).

Famous quotes containing the word bond:
“When the bond of love broke,
the respect born of affection withered,
good feelings fled,
and that man walked before me
like any other,
Good Friend,
I imagine all this,
think on days gone by
and wonder why
my heart hasn’t cracked
into a hundred bits.”
—Amaru (c. seventh century A.D.)
