Metabolite Identification
Common NameTricosane
Description, also known as N-tricosane or CH3-[CH2]21-CH3, belongs to the class of organic compounds known as alkanes. These are acyclic branched or unbranched hydrocarbons having the general formula CnH2n+2 , and therefore consisting entirely of hydrogen atoms and saturated carbon atoms. Thus, is considered to be a hydrocarbon lipid molecule. exists as a solid and is considered to be practically insoluble (in water) and relatively neutral. has been primarily detected in saliva. can be converted into 22-methyltricosan-1-ol and tricosan-1-ol. is an alkane and waxy tasting compound that can be found in a number of food items such as coconut, papaya, allspice, and kohlrabi. This makes a potential biomarker for the consumption of these food products.
