Hydroquinone

Hydroquinone, lead (2+) salt (2:1)

C6H6O2 (110.0367776)


Hydroquinone, also benzene-1,4-diol, is an aromatic organic compound which is a type of phenol, having the chemical formula C6H4(OH)2. Its chemical structure has two hydroxyl groups bonded to a benzene ring in a para position. Hydroquinone is commonly used as a biomarker for benzene exposure. The presence of hydroquinone in normal individuals stems mainly from direct dietary ingestion, catabolism of tyrosine and other substrates by gut bacteria, ingestion of arbutin containing foods, cigarette smoking, and the use of some over-the-counter medicines. Hydroquinone is a white granular solid at room temperature and pressure. The hydroxyl groups of hydroquinone are quite weakly acidic. Hydroquinone can lose an H+ from one of the hydroxyls to form a monophenolate ion or lose an H+ from both to form a diphenolate ion. Hydroquinone has a variety of uses principally associated with its action as a reducing agent which is soluble in water. It is a major component in most photographic developers where, with the compound Metol, it reduces silver halides to elemental silver. [HMDB]. Hydroquinone is found in many foods, some of which are kai-lan, agar, red bell pepper, and jostaberry.

C30H50O (426.386145)


Epi-alpha-amyrin, also known as epi-α-amyrin, is a member of the class of compounds known as triterpenoids. Triterpenoids are terpene molecules containing six isoprene units. Epi-alpha-amyrin is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). Epi-alpha-amyrin can be found in herbs and spices, pomes, and rosemary, which makes epi-alpha-amyrin a potential biomarker for the consumption of these food products.

Hexacosyl alcohol

C26H54O (382.41744339999997)


Hexacosan-1-ol, also known as 1-hexacosanol or hexacosyl alcohol, is a member of the class of compounds known as fatty alcohols. Fatty alcohols are aliphatic alcohols consisting of a chain of a least six carbon atoms. Thus, hexacosan-1-ol is considered to be a fatty alcohol lipid molecule. Hexacosan-1-ol is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). Hexacosan-1-ol can be synthesized from hexacosane. Hexacosan-1-ol can also be synthesized into 24-methylhexacosan-1-ol. Hexacosan-1-ol can be found in a number of food items such as brussel sprouts, broccoli, lemon grass, and lettuce, which makes hexacosan-1-ol a potential biomarker for the consumption of these food products. Hexacosan-1-ol is a saturated primary fatty alcohol with a carbon chain length of 26 that is a white waxy solid at room temperature. It is freely soluble in chloroform and insoluble in water. It occurs naturally in the epicuticular wax and plant cuticle of many plant species .
