| Description | D-Alanyl-D-alanine, also known as D-ala-D-ala or ala-ala, belongs to the class of organic compounds known as dipeptides. These are organic compounds containing a sequence of exactly two alpha-amino acids joined by a peptide bond. D-Alanyl-D-alanine is a very strong basic compound (based on its pKa). D-Alanyl-D-alanine exists in all living organisms, ranging from bacteria to humans. (2r)-2-{[(2r)-2-amino-1-hydroxypropylidene]amino}propanoic acid is found in Homo sapiens, Oryza punctata and Trypanosoma brucei. (2r)-2-{[(2r)-2-amino-1-hydroxypropylidene]amino}propanoic acid was first documented in 1981 (PMID: 6118181). A dipeptide comprising D-alanine with a D-alanyl residue attached to the alpha-nitrogen (PMID: 6423541) (PMID: 16030213) (PMID: 17418637). |
