Muscle Malonyl Coa Biomarker Assay Development

Collection of muscle biopsies of the vastus lateralis will be performed by a consulting specialist. The first muscle biopsy (Day 1, 2 hour) will be obtained from the vastus lateralis muscle of the non-dominant leg. The second biopsy (Day 1, 4 hour) will be obtained from the same vastus lateralis muscle on the same leg approximately 10 centimeters from the first muscle biopsy site.
