Effects
Effects
N-Acetyl-D-Neuraminic Acid
N-acetyl-D-neuraminic acid (also known as Neu5Ac or NANA) is the most common and physiologically relevant form of sialic acid in the human body. As a terminal monosaccharide unit, it plays a central role in the structure of the glycocalyx – a complex sugar layer surrounding every cell – and is an essential component of numerous glycoproteins and glycolipids on the surface of cell membranes. There, it contributes to the negative charge of the cell and is crucial for intercellular communication as well as the body's recognition processes.
