Advanced glycation end-products (AGEs)

Advanced glycation end-products are stable, often crosslinked compounds formed when sugars react with proteins, lipids, or DNA over time. They accumulate in long-lived tissues such as skin, cartilage, and arterial walls, where they impair elasticity and function. AGEs activate the RAGE receptor, triggering inflammation and oxidative stress. Their build-up is linked to diabetes complications, atherosclerosis, kidney disease, and skin ageing.
