Description | Cyclo(leu-phe), also known as cyclo(Phe-leu) or cFL, is classified as an alpha amino acid or an Alpha amino acid derivative. Alpha amino acids are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon), or a derivative thereof. Cyclo(leu-phe) is considered to be a practically insoluble (in water) and a moderately acidic compound. Cyclo(leu-phe) can be found in feces. |
