Stimulation of pancreatic islet metabolism and insulin release by a nonmetabolizable amino acid.


The leucine analog beta-2-aminobicyclo[2.2.1]heptane-2-carboxylic acid (BCH) activates glutamate dehydrogenase [L-glutamate:NAD+ oxidoreductase (deaminating), EC] in pancreatic islet homogenates. In intact islets, BCH increased the islet content or output of NH4+, 2-ketoglutarate, malate, pyruvate, and alanine. BCH caused a dose-related increase in… (More)
