Dipeptides are organic compounds containing a sequence of exactly two alpha-amino acids joined by a peptide bond. Alanyl-alanine is soluble (in water) and a weakly acidic compound (based on its pKa). Alanyl-alanine can be found in chives, which makes alanyl-alanine a potential biomarker for the consumption of this food product. Alanyl-alanine can be found primarily in feces. Alanyl-alanine exists in all living organisms, ranging from bacteria to humans. α-alanylalanine Ala-ala Alanine, n-DL-alanyl-, DL- Alanine, n-l-alanyl-, l- Di-l-alanine DL-ala-DL-ala DL-alanine, n-DL-alanyl- DL-Alanine, N-DL-alanyl- (9CI) DL-alanyl-DL-alanine DL-alanyl-l-alanine L-alanine, n-l-alanyl- L-alanyl-l-alanine N-(2-Aminopropanoyl)alanine N-DL-alanyl-DL-alanine C6H12N2O3 160.1711 160.08479226 (2S)-2-[(2S)-2-aminopropanamido]propanoic acid (2S)-2-[(2S)-2-aminopropanamido]propanoic acid 1948-31-8 CC(N)C(O)=NC(C)C(O)=O InChI=1S/C6H12N2O3/c1-3(7)5(9)8-4(2)6(10)11/h3-4H,7H2,1-2H3,(H,8,9)(H,10,11) DEFJQIDDEAULHB-UHFFFAOYSA-N belongs to the class of organic compounds known as dipeptides.
