Brief Summary:
This study will evaluate the branched-chain amino acids (BCAA) ratio in the medical foods formulated for Methylmalonic and Propionic Acidemias (MMA/PROP) patients. We will recruit 6 healthy children between 6-10y (3 boys and 3 girls). They will be given amino acid-based shakes and protein free cookies. Using a minimally invasive stable isotope based technique, we will be able to determine the optimal ratio of BCAA to be added in the medical foods for the MMA/PROP subjects.

Arm Intervention/treatment
Experimental: BCAA Ratio
Different Branched-chain amino acid (BCAA) ratios will be tested. BCAA are comprised of 3 different amino acids (leucine, isoleucine and valine). The ratios among these 3 amino acids will be tested at 6 different ratios. Each intervention will be for 8hours.
Dietary Supplement: L-Amino Acids
6 different ratios of the Branched-chain Amino Acids (BCAA) will be tested for 8 hours each.




Primary Outcome Measures :
  1. 13C Phenylalanine Oxidation [ Time Frame: 8 hours ]
    Breath and Urine samples will be collected during the study to measure 13C Phenylalanine oxidation


Secondary Outcome Measures :
  1. Urinary Branched Chain amino acids excretion [ Time Frame: 8 hours ]
    Urine samples will be collected during the study to measure BCAA urinary excretion
