Glykering

Glykering is a biochemical process that involves the formation of covalent bonds between glucose molecules and proteins, lipids, or other macromolecules within living organisms. This non-enzymatic reaction is a fundamental aspect of glycation, which differs from enzymatic glycosylation in that it occurs spontaneously under physiological conditions. Glykering typically happens when excess glucose in the bloodstream reacts with amino groups on proteins, forming stable, advanced glycation end-products (AGEs).

This process plays a significant role in aging and the development of various diseases, particularly diabetes-related complications. Elevated blood glucose levels accelerate glycation, leading to the accumulation of AGEs in tissues such as blood vessels, skin, and organs. These AGEs can induce structural and functional alterations by cross-linking collagen and other structural proteins, thereby impairing tissue elasticity and function. They are also known to interact with specific cell surface receptors, triggering inflammatory responses and oxidative stress.

Glykering is distinct from glycosylation, a regulated enzymatic process essential for cell signaling, immune response, and protein stability. While glycation is generally considered deleterious, in some cases, it plays roles in natural processes such as wound healing.

Research continues to explore therapeutic strategies aimed at inhibiting glycation or breaking AGE cross-links to mitigate its adverse effects. Understanding glykering is vital for developing interventions for diabetic complications, aging-related tissue deterioration, and other metabolic disorders. The study of glykering also emphasizes the importance of controlling blood glucose levels to prevent or slow the progression of AGE-related tissue damage.
