D(-)-allo-Threonine Chemical Properties,Usage,Production
Description
D(-)-allo-Threonine is an isomer of threonine. It is found as a constituent of an increasing group of biologically active peptides. Stereocontrolled syntheses of chiral and racemic key intermediates to thienamycin can be achieved from d-allo-threonine and trans-crotonic acid.

Chemical Properties
white crystalline powder
Uses
They are found as constituents of an increasing group of biologically active peptides. Stereocontrolled syntheses of chiral and racemic key intermediates to thienamycin from d-allo-threonine and trans-crotonic acid.
Definition
ChEBI: D-allothreonine is the D-enantiomer of allothreonine. It occurs as a component of peptido-lipids in certain bacteria. It has a role as a bacterial metabolite. It is an allothreonine and a D-alpha-amino acid. It is an enantiomer of a L-allothreonine. It is a tautomer of a D-allothreonine zwitterion.
Purification Methods
Recrystallise D-allothreonine from aqueous EtOH or 50% EtOH. [Elliot J Chem Soc 62 1950, Birnbaum et al. J Biol Chem 194 455 1952, IR: Greenstein & Winitz The Chemistry of the Amino Acids J. Wiley, Vol 3 1961, Beilstein 4 IV 3170.]
