Allothreonine
Chemical compound / From Wikipedia, the free encyclopedia
Allothreonine is an amino acid with the formula CH3CH(OH)CH(NH2)CO2H. It is the diastereomer of the amino acid threonine. Like most other amino acids, allothreonine is a water-soluble colorless solid. Although not one of the proteinogenic amino acids, it has often been the subject for the synthesis of novel proteins using an expanded genetic code.[1] Racemic allothreonine can be produced in the laboratory from bromomethoxybutyric acid.[2]
