4-Amino-5-hydroxymethyl-2-methylpyrimidine
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
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.
