Metabolite Identification
Common Name2,4-Diaminobutyric acid
Description2,4-Diaminobutyric acid, also known as 2,4-diaminobutanoate or Dbu, belongs to the class of organic compounds known as alpha amino acids. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). 2,4-Diaminobutyric acid is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. 2,4-Diaminobutyric acid exists in all living organisms, ranging from bacteria to humans.
