Carbohydrate recognition domains (CRDs)

Carbohydrate recognition domains (CRDs) are specialized parts of proteins that can recognize and bind to specific sugar molecules (carbohydrates). These domains play a crucial role in various biological processes, such as cell communication, immune responses, and pathogen recognition. By identifying and attaching to different carbohydrates on the surfaces of cells or microorganisms, CRDs help the body distinguish between healthy cells and potential threats, like bacteria or viruses. They are significant in research and medicine, as they can be targeted for developing treatments or vaccines.
