Metabolite Identification
Common NameCysteinyl-Asparagine
DescriptionCysteinyl-asparagine, also known as C-N dipeptide or cys-asn, 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. Cysteinyl-asparagine is possibly soluble (in water) and a very strong basic compound (based on its pKa).
