Aspartylphenylalanine
Aspartylphenylalanine is a dipeptide composed of aspartate and phenylalanine, and is a metabolic byproduct of its methyl ester, aspartame (Nutrasweet). After hydrolysis of the ester bond in the intestinal lumen, the dipeptide is apparently absorbed and digested in the same manner as dipeptides derived from protein digestion. There are several Asp-Phe dipeptidases that degrade this peptide. It has been suggested that individuals with aspartame allergies may be deficient in this peptidase (PMID: 3743970). It has been observed that N-beta-aspartylphenylalanine (a breakdown product of Asp-Phe) is a naturally occurring peptide found in both blood and urine (PMID: 2723819).
Degradation product of Aspartame
Phenylalanylaspartic acid
Phenylalanylaspartic acid is a dipeptide composed of phenylalanine and aspartic acid. It is an incomplete breakdown product of protein digestion or protein catabolism. Dipeptides are organic compounds containing a sequence of exactly two alpha-amino acids joined by a peptide bond. Some dipeptides are known to have physiological or cell-signalling effects although most are simply short-lived intermediates on their way to specific amino acid degradation pathways following further proteolysis.
L-beta-aspartyl-L-phenylalanine
L-beta-aspartyl-l-phenylalanine 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 his terminal nitrogen atom. It is found in urine (PMID: 3782411). A dipeptide found in urine (PMID: 3782411). This is a proteolytic breakdown product of larger proteins. [HMDB]

fumisoquin A
A pyridoisoquinoline that is (11aR)-1,3,4,6,11,11a-hexahydro-2H-pyrido[1,2-b]isoquinoline substituted by hydoxy groups at positions 1S,7,8 and 11R, by an amino group at position 3S and an oxo group at position 4. It is produced by a biosynthetic gene cluster called fsq in the human pathogen Aspergillus fumigatus.
