4-heptanone
propyl ketone
 
Notes:
marker in diabetes mellitus urine. Flavouring ingredient Is a volatile organic ketone found in almost all urine samples of normal individuals. (PMID 15996539); It has been hypothesized that arises from in vivo beta-oxidation of 2-ethylhexanoic acid (EHA) from plasticizers, similar to formation of 3-heptanone from valproic acid.
