Quote by Ed Yong
““Mucus is made from giant molecules called mucins, each consisting of a central protein backbone with thousands of sugar molecules branching off it. These sugars allow individual mucins to become entangled, forming a dense, nearly impenetrable thicket – a Great Wall of Mucus that stops wayward microbes from penetrating deeper into the body. And if that wasn’t deterrent enough, the wall is manned by viruses.””
