tropinone

8-methyl-8-azabicyclo[3.2.1]octan-3-one

C8H13NO (139.0997)

Tropinone, also known as 3-tropanone, is a member of the class of compounds known as tropane alkaloids. Tropane alkaloids are organic compounds containing the nitrogenous bicyclic alkaloid parent N-Methyl-8-azabicyclo[3.2.1]octane. Tropinone is soluble (in water) and an extremely weak acidic compound (based on its pKa). Tropinone can be found in a number of food items such as walnut, japanese persimmon, komatsuna, and chicory roots, which makes tropinone a potential biomarker for the consumption of these food products. Tropinone is an alkaloid, famously synthesised in 1917 by Robert Robinson as a synthetic precursor to atropine, a scarce commodity during World War I. Tropinone and the alkaloids cocaine and atropine all share the same tropane core structure. Its corresponding conjugate acid at pH 7.3 major species is known as tropiniumone . KEIO_ID T061 Tropinone, an alkaloid, acts as a synthetic intermediate to?Atropine[1].

4-Amino-5-hydroxymethyl-2-methylpyrimidine

4-Amino-2-methyl-5-hydroxymethylpyrimidine

C6H9N3O (139.0746)

Hydroxymethylpyrimidine, also known as pyramine or toxopyrimidine, is a member of the class of compounds known as hydropyrimidines. Hydropyrimidines are compounds containing a hydrogenated pyrimidine ring (i.e. containing less than the maximum number of double bonds.). Hydroxymethylpyrimidine is soluble (in water) and a very weakly acidic compound (based on its pKa). Hydroxymethylpyrimidine can be found in a number of food items such as mexican oregano, sugar apple, tronchuda cabbage, and cinnamon, which makes hydroxymethylpyrimidine a potential biomarker for the consumption of these food products. Hydroxymethylpyrimidine exists in E.coli (prokaryote) and yeast (eukaryote).

Histidinal

(AlphaS)-alpha-amino-1H-imidazole-5-propanal

C6H9N3O (139.0746)

Histidinal (CAS: 23784-33-0), also known as histidinaldehyde, belongs to the class of organic compounds known as aralkylamines. These are alkylamines in which the alkyl group is substituted at one carbon atom by an aromatic hydrocarbyl group. Histidinal is a very strong basic compound (based on its pKa). Histidinal is involved in the histidine biosynthesis pathway. Histidinal is produced by the reaction between histidinol and NAD+, with NADH as a byproduct. The reaction is catalyzed by histidinol dehydrogenase. Histidinal reacts with NAD+ and H2O to produce L-histidine and NADH. Histidinol dehydrogenase catalyzes this reaction. Histidinal is involved in the histidine biosynthesis I pathway.

2-Methylaminoethylphosphonate

N-Monomethyl-2-aminoethylphosphonate

C3H10NO3P (139.0398)

Supinidine

[(7aS)-2,3,5,7a-tetrahydro-1H-pyrrolizin-7-yl]methanol

C8H13NO (139.0997)

Supinidine is soluble (in water) and an extremely weak acidic compound (based on its pKa). Supinidine? can be found in borage, which makes supinidine? a potential biomarker for the consumption of this food product.
