Metabolite Identification
Common NameN-Heptane
Description, also known as N-heptane or CH3-[CH2]5-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. Within the cell, is primarily located in the membrane (predicted from logP). is also a parent compound for other transformation products, including but not limited to, 4-heptanone, 2-isopropyl-5-methyl-1-heptanol, and heptane-1,2,3-triol. is a sweet, alkane, and ethereal tasting compound that can be found in cardamom and ginger. This makes a potential biomarker for the consumption of these food products. is a potentially toxic compound.
