Figure 1. Effect of Diapin on blood glucose levels in C57BL/6J mice during OGTT.

Figure 1

A. Effect of Diapin on blood glucose. The mice were fasted overnight and orally loaded with glucose (2 mg/g, bw) in the control (n = 10) and glucose (2 mg/g) plus Diapin (4 µmol/g, equal to 1 mg/g) in the treated group (n = 10). B. Effect of the amino acids of Diapin on blood glucose. In the treated group (n = 10), the mice were loaded with glucose and mixture of amino acids of Diapin (G, G, L; 4 µmol/g for each amino acid). C. Effect of the dipeptides on blood glucose. In the treated groups, the mice were loaded with glucose and dipeptides (GG or GL, 4 µmol/g). D. Effect of a control peptide on blood glucose. In the treated group (n = 10), the mice were loaded with glucose and a tripeptide (4 µmol/g). Blood glucose levels were measured every 30 min after glucose loading. *P<0.05, compared with the controls.
