Influence of the Ingestion of Branched Chain Amino Acids on Plasma Concentrations of Ammonia and Free Fatty Acids In this study, 10 volunteers underwent multiple blood draws after ingesting 20 g of branched chain amino acids (BCAA) to determine plasma modifications of BCAA and their effects on ammonia and FFA in peripheral blood. Subjects were kept resting during the 2-hr study period. There was a rapid increase in BCAA concentrations (350% basal values 90 min from the BCAA load and 260% basal values at 120 min) of ammonia (160% basal values at 90 min) and of FFA (at least 300% basal values for 120 min). It is hypothesized that rapid increases of BCAA plasma concentrations, as induced in resting individuals by ingestion of 20 g of BCAA, can stimulate FFA release from adipose tissue, thus contributing to glucose sparing and amino acid drive to oxidation. Transamidation of 3% of the ingested BCAA would be sufficient to match for the observed ammonia modifications. Source Journal Strength Conditioning Research
