Is the small intestine a gluconeogenic organ

Abstract:
Gluconeogenesis is responsible for the maintenance of blood glucose levels as hepatic glycogen stores become depleted. Traditionally, only liver and kidney have been believed to be capable of gluconeogenesis, but a gluconeogenic capacity for the small intestine has recently been proposed. This possibility is supported by the expression of key gluconeogenic enzymes and radiolabeled tracer experiments, but these data are not unequivocal and alternative roles can explain the presence of gluconeogenic enzymes in this organ.

Small Intestine
The small intestine is divided into three main sections - the duodenum, jejunum, and ileum. The duodenum, approximately 25 cm long, is nearest the stomach. It acts as a 'mixing bowl,' where chyme (partially digested food) blends with digestive enzymes from the pancreas and liver. The duodenum's unique C-shape wraps...
