N-linked glycosylation

N-linked glycosylation is a cellular process where sugars are attached to specific proteins, particularly within the endoplasmic reticulum and Golgi apparatus of cells. This modification plays a crucial role in determining a protein's structure, stability, and function, affecting how it behaves in the body. Think of it as a postal system where proteins receive "mail" in the form of sugar chains that help guide them to their correct destinations or ensure they work properly. This process is vital for many biological functions, including immune responses and cell communication.
