Following its release, GLP-1(736) is quickly degraded by dipeptidyl peptidase 4 (DPP-4) to form the metabolite GLP-1(936), which lacks insulin-releasing capacity [7], and only 1015% of the GLP-1 released in the gut reaches the pancreatic islets [5]
This is the core problem with treating a GLP-1 as a standalone fix rather than one piece of a larger plan
Notably, hydrogen bonds, which account for the high affinity, are formed between DEHP and proteins due to the four hydrogen bond receptors of the carboxyl groups, including ASN-51 of HSP90AA1, ARG-24 of IL6, LYS-54 of MAPK1, GLN-20 of BCL2, GLN-20 of EP300, ARG-207 of CASP3, GLN-68 and THR-45 of ERBB2, LYS-87 of BCL2L1, and ARG-112 of GRB2
