O-glycan

O-glycans are a type of carbohydrate found in the outermost layer of cells and in the extracellular matrix of tissues, providing structural support and recognition for proteins. They are made up of short chains of monosaccharides connected by a glycosidic bond and are essential for the normal functioning of the cell. O-glycans have the potential to modulate the activity of proteins and regulate cellular processes, playing a critical role in cellular signaling, cellular homeostasis, and immune responses. They are involved in many diseases and are being studied as potential therapeutic targets. O-glycans can also be used in biomarker discovery, diagnostics, and drug development.
