Diаbetes is а metаbоlic disоrder characterized by chrоnic hyperglycemia, which affects oxygen delivery in the body through its impact on hemoglobin and blood pH. In individuals with poorly controlled diabetes, elevated blood glucose levels lead to the non-enzymatic glycation of hemoglobin, forming glycated hemoglobin (HbA1c). This modification alters the structural and functional properties of hemoglobin, impacting its ability to transition between the T (tense) and R (relaxed) states. The Bohr effect, which describes hemoglobin's pH-dependent oxygen-binding affinity, is also influenced in diabetic patients. Hyperglycemia-induced metabolic acidosis, due to the buildup of lactic acid and ketone bodies (e.g., in diabetic ketoacidosis), lowers blood pH in tissues. This acidic environment stabilizes hemoglobin in its T state, reducing oxygen affinity and promoting oxygen release. However, in the lungs, where blood pH is typically higher, the R state predominates, allowing oxygen loading to proceed efficiently. Additionally, chronic hyperglycemia can impair capillary blood flow and oxygen delivery to tissues, exacerbating hypoxia in metabolically active regions. This can amplify the T state stabilization, especially in peripheral tissues. Diabetic patients may thus experience diminished oxygen delivery efficiency, particularly under conditions of increased metabolic demand. How does glycation of hemoglobin affect its structural ability to transition between the T and R states?
