Little information is available on amino acids (AA) as alternative energy-source in diabetes. To study the interaction between insulin-stimulated glucose and AA utilization in normal and diabetic subjects, intraportal hyperinsulinaemic euglycaemic euaminoacidaemic clamp studies were performed in normal (n=8) and streptozotocin (120 mg/kg) induced diabetic (n=7) pigs of ~40-45 kg.<h4>Results</h4>Diabetic vs normal pigs showed basal hyperglycaemia (19.0±2.0 vs 4.7±0.1 mmol/L, P<.001) and at the level of individual AA, basal concentrations of valine and histidine were increased (P<.05) whereas tyrosine, alanine, asparagine, glutamine, gluBMC biochemistry25https://www.ebi.ac.uk/biostudies/studies/S-EPMC3129298biostudies-literatureThe existence of an insulin-stimulated glucose and non-essential but not essential amino acid substrate interaction in diabetic pigs.PMC3129298Koopmans SJWijdenes JVanderMeulen JCorbijn HDekker RfalseThe existence of an insulin-stimulated glucose and non-essential but not essential amino acid substrate interaction in diabetic pigs.<h4>Background</h4>The generation of energy from glucose is impaired in diabetes and can be compensated by other substrates like fatty acids (Randle cycle).
