A normal glycocalyx is crucial for a Normal glycocalyx APP Cell membrane Alzheimer glycocalyx Beta-amyloid plaques Truncated APP Normal versus Alzheimer-affected glycocalyx. A molecular forest called the glycocalyx covers all cells. An important member of a neuron’s glycocalyx is a molecule called amyloid precursor protein (APP). In Alzheimer’s disease, APP is cut into two pieces, forming truncated APP and beta-amyloid. The truncated APP (tAPP) remains in the membrane, while the beta-amyloid forms extracellular deposits known as plaques.
