WebAbstract. If glucagon plays a hormonal role in the regulation of gluconeogenesis from endogenous amino acids, its secretion might be stimulated by an increase in the concentration of alanine, which has recently been identified as a principal gluconeogenic precursor. To determine if this is the case, 0.75 mmole of alanine per kilo was infused ... WebIn type 2 diabetes (T2D), gluconeogenesis is a main cause of the elevated hepatic glucose output and is largely responsible for the elevated fasting glucose level. Pyruvate is the pivotal substrate for gluconeogenesis via rate-limiting enzyme, phosphoenolpyruvate carboxykinase (PEPCK), which is normally suppressed by insulin.
