The Full Form of DTT is Dithiothreitol.
Dithiothreitol (DTT) is the common name for a small-molecule redox reagent also known as Cleland’s reagent. DTT’s formula is C4H10O2S2 and the chemical structure of one of its enantiomers in its reduced form is shown on the right; its oxidized form is a disulfide bonded 6-membered ring (shown below). The reagent is commonly used in its racemic form, as both enantiomers are reactive. Its name derives from the four-carbon sugar, threose. DTT has an epimeric (‘sister’) compound, dithioerythritol (DTE).
