Description | Leucyl-phenylalanine, also known as (2s,3s)-(2-2h,3-2h)-leucine-(S)-phenylalanine or leu-phe, is a member of the class of compounds known as dipeptides. Dipeptides are organic compounds containing a sequence of exactly two alpha-amino acids joined by a peptide bond. Leucyl-phenylalanine is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Leucyl-phenylalanine can be found primarily in blood, feces, and urine. |
