N-glycosylation

N-glycosylation is a biological process where sugar molecules are attached to specific nitrogen atoms on a protein. This modification occurs in the cell’s endoplasmic reticulum and Golgi apparatus, helping proteins fold correctly, remain stable, and function properly. It also influences how proteins interact with other molecules and their lifespan in the body. Essentially, N-glycosylation adds sugar chains to proteins, serving as a form of cellular "labeling" that affects protein behavior and activity within living organisms.
