In ACS' monthly publication the Journal of Proteome Research (Aug. 7th issue) scientists report evidence from studies in humans for the existence of unique patterns in metabolism.
Fingerprints move over. Scientists are reporting evidence that people have another defining trait that may distinguish each of the 6.7 billion humans on Earth from one another almost as surely as the arches, loops, and whorls on their fingertips.
Metabolism is a whole caboodle of chemical processes. The body uses to turn food into energy, grow, repair damage from diseases and injuries, use medicines, and carry out other functions necessary to continue living. In the new study, Ivano Bertini and colleagues cite growing evidence that each individual has a unique metabolic profile. It's a biochemical counterpart to fingerprints that can be detected by analyzing the chemical whorls and grooves that result from metabolism and can be detected in the urine.
