UNC Nutrition Obesity Research Center (NORC)
Metabolism and Metabolomics Core


The Metabolism and Metabolomics Core provides cutting edge nutritional metabolomics services, biochemistry methods, and molecular biology techniques for nutrition research.

The goals of our core are to encourage and facilitate the use of biomarkers for nutritional epidemiological and intervention studies, to provide access to state-of-the-art techniques and equipment to bench scientists, and to provide cost-effective assays for investigators without lab facilities. The core also provides training for students and postdoctoral fellows. With locations at both the Chapel Hill and Nutrition Research Institute (NRI) campuses, we are able to provide a wide array of instrumentation and support to investigators at both locations.

Additionally, metabolomics – the profiling of the many small molecules in blood, urine, or tissues – provides an opportunity for investigators to obtain a snapshot of metabolism. The metabolomics lab, located at NRI, is working to make personalized medicine a reality through metabolomics. Metabolomic analyses provide a more comprehensive view of a patient’s metabolism than the limited measurements of glucose and cholesterol that doctors employ today. Using metabolomics, the lab assesses differences in the metabolic profile of individuals that correlate with states of wellness or disease.

The Atomic Absorption Spectroscopy Lab provides analysis that is used to determine the levels of arsenate, methylated and other organic forms of arsenic in solutions and/or matrices.


The Metabolism and Metabolomics Core offers a variety of services. To learn more about a specific service and/or to submit a service request, visit us on iLab.
