Description
D-Allothreonine is the D type stereoisomer of Allothreonine. D-Allothreonine is a peptido-lipid derived from bacteria. D-Allothreonine, amide-linked to the D-galacturonic acid, is also a constituent in the polysaccharide[1][2].
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.
