Pyriculol
A benzaldehyde that is salicylaldehyde which is substituted at position 6 by a (3R,4S,5E)-3,4-dihydroxyhepta-1,5-dien-1-yl group. It is a phytotoxic metabolite, isolated from the rice blast fungi Magnaporthe oryzae and Magnaporthe grisea.
Mycorradicin
Mycorradicin is a member of the class of compounds known as medium-chain fatty acids. Medium-chain fatty acids are fatty acids with an aliphatic tail that contains between 4 and 12 carbon atoms. Mycorradicin is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Mycorradicin can be found in corn, which makes mycorradicin a potential biomarker for the consumption of this food product.

Glutamylthreonine
C9H16N2O6 (248.10083160000002)
Glutamylthreonine is a dipeptide composed of glutamate and threonine, 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. Glutamylthreonine 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-Glutamylthreonine
C9H16N2O6 (248.10083160000002)
gamma-Glutamylthreonine is a dipeptide composed of gamma-glutamate and threonine, 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-Glutamylthreonine 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.
