Carbohydrate recognition domains

Carbohydrate recognition domains (CRDs) are specialized parts of certain proteins that allow them to detect and bind specific sugar molecules (carbohydrates). These domains act like molecular "hands" that recognize distinct sugar structures on cell surfaces or in the environment. CRDs are essential for processes like immune response, cell signaling, and pathogen detection. By precisely recognizing particular sugars, these protein domains help cells communicate, identify threats, or interact with their surroundings effectively, playing a crucial role in maintaining health and immune defense.
