1,4-Dihydroxy-2-naphthoic acid
1,4-dihydroxy-2-naphthoate, also known as 1,4-dihydroxy-2-naphthalenecarboxylic acid, is a member of the class of compounds known as naphthalenecarboxylic acids. Naphthalenecarboxylic acids are compounds containing a naphthalene moiety, which bears a carboxylic acid group one or more positions. Naphthalene is a bicyclic compound that is made up of two fused benzene ring. 1,4-dihydroxy-2-naphthoate is practically insoluble (in water) and a moderately acidic compound (based on its pKa). 1,4-dihydroxy-2-naphthoate can be synthesized from 2-naphthoic acid. 1,4-dihydroxy-2-naphthoate can also be synthesized into 1,4-dihydroxy-2-naphthoyl-CoA. 1,4-dihydroxy-2-naphthoate can be found in a number of food items such as rowal, cinnamon, breadfruit, and horseradish, which makes 1,4-dihydroxy-2-naphthoate a potential biomarker for the consumption of these food products.
7,7,8,8-Tetracyanoquinodimethane
Rapalexin A
Rapalexin a is a member of the class of compounds known as indoles. Indoles are compounds containing an indole moiety, which consists of pyrrole ring fused to benzene to form 2,3-benzopyrrole. Rapalexin a is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Rapalexin a can be found in chinese cabbage, which makes rapalexin a a potential biomarker for the consumption of this food product.
Angelical
Angelical, also known as 7-methoxy-2-oxo-2h-1-benzopyran-6-carboxaldehyde or 6-formyl-7-methoxycoumarin, belongs to coumarins and derivatives class of compounds. Those are polycyclic aromatic compounds containing a 1-benzopyran moiety with a ketone group at the C2 carbon atom (1-benzopyran-2-one). Angelical is practically insoluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). Angelical can be found in sweet orange, which makes angelical a potential biomarker for the consumption of this food product.
