Diethylstilbestrol
Diethylstilbestrol is a synthetic estrogen that was developed to supplement a womans natural estrogen production. In 1971, the Food and Drug Administration (FDA) issued a Drug Bulletin advising physicians to stop prescribing DES to pregnant women because it was linked to a rare vaginal cancer in female offspring. Diethylstilbesterol is found in gram bean. Diethylstilbestrol is a synthetic nonsteroidal estrogen used in the treatment of menopausal and postmenopausal disorders. It was also used formerly as a growth promoter in animals. According to the Fourth Annual Report on Carcinogens (NTP 85-002, 1985), diethylstilbestrol has been listed as a known carcinogen.

Histidylleucine
Histidylleucine is a dipeptide composed of histidine and leucine. 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.
4-METHYL-2,4-BIS(4-HYDROXYPHENYL)PENT-1-ENE
Isoleucyl-Histidine
Isoleucyl-Histidine is a dipeptide composed of isoleucine and histidine. It 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. This dipeptide has not yet been identified in human tissues or biofluids and so it is classified as an Expected metabolite.
Histidylisoleucine
Histidylisoleucine is a dipeptide composed of histidine and isoleucine. 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.
Leucyl-Histidine
Leucyl-Histidine is a dipeptide composed of leucine and histidine. It 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. This dipeptide has not yet been identified in human tissues or biofluids and so it is classified as an Expected metabolite.

Estrogen
A steroid hormone that stimulates or controls the development and maintenance of female sex characteristics in mammals by binding to oestrogen receptors. The oestrogens are named for their importance in the oestrous cycle. (ChEBI). Estrogen is found in date and apricot.
