Cyclo(Leu-Phe)
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.

Gamma-glutamyl-leucine
gamma-Glutamylleucine is a dipeptide composed of gamma-glutamate and leucine, and is a proteolytic breakdown product of larger proteins. It belongs to the family of N-acyl-alpha amino acids and derivatives. These are compounds containing an alpha amino acid which bears an acyl group at its terminal nitrogen atom. gamma-Glutamylleucine is an incomplete breakdown product of protein digestion or protein catabolism. Some dipeptides are known to have physiological or cell-signaling effects although most are simply short-lived intermediates on their way to specific amino acid degradation pathways following further proteolysis. gamma-Glutamylleucine is a biomarker for the consumption of whey protein. It is found in urine (PMID: 3782411). Gamma-glutamylleucine, also known as gamma-glutamyl-leucine, (d,l)-isomer or L-gamma-glu-L-leu, 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. Gamma-glutamylleucine is slightly soluble (in water) and a moderately acidic compound (based on its pKa). Gamma-glutamylleucine can be found in soft-necked garlic, which makes gamma-glutamylleucine a potential biomarker for the consumption of this food product. Gamma-glutamylleucine can be found primarily in blood and feces. H-γ-Glu-Leu-OH is a dipeptide consisting of γ-glutamic acid and leucine, terminated by a hydroxyl group[1].
