Blood glucose regulatory and metabolic enzymes

Blood glucose regulatory and metabolic enzymes represent a broad functional category of proteins that orchestrate the maintenance of systemic glycemic levels. This group encompasses a variety of enzymes with distinct locations and roles, such as intestinal alpha-glucosidases that catalyze the breakdown of complex carbohydrates into absorbable monosaccharides (NIH, 2023). It also includes dipeptidyl peptidase-4 (DPP-4), a protease that degrades incretin hormones like GLP-1, thereby influencing insulin secretion and glucagon suppression (StatPearls, 2023). Furthermore, hepatic enzymes such as glucose-6-phosphatase and phosphoenolpyruvate carboxykinase (PEPCK) are pivotal in controlling endogenous glucose production via gluconeogenesis and glycogenolysis (PubMed, 2022). Because these enzymes are central to metabolic homeostasis, they are primary targets for pharmacological intervention in the management of Type 2 diabetes mellitus. However, the term refers to a collective class of enzymes rather than a single specific molecular target, making it a functional grouping used in metabolic research and drug classification.
