Background: PYY (1-36), a polypeptide consisting of 36 amino acid structures, is known to play a role in increasing the growth and survival of beta cells through NPY1R activation in the pancreas, which ultimately leads to glycemic balance. (P3L31P34)PYY(1-36) is a PYY (1-36) analog that is resistant to DPP-IV degradation and has high selectivity to NPY1R. This study aims to identify the charact…
