N-acetylglucosamine

N-acetylglucosamine (commonly called GlcNAc) is a natural sugar molecule that plays a key role in the structure and function of various biological components. It is a building block for chitin, which forms the shells of insects and the exoskeletons of crustaceans, as well as for certain components of the human body's cell walls and connective tissues. GlcNAc is also involved in important biological processes like cell signaling and immune response. Its presence helps maintain the strength and integrity of tissues, making it essential for overall health and structural support.
