Well, basically these red oligosaccharides contain modified sugar molecules that contain negative charges and these negative charges attract water molecules which are polar molecules. And so as a result of those charges we're basically going to have many of these water molecules which are basically going to surround this entire mucin molecule. And as a result that basically gives the addition of these sugar molecules, gives the mucins, these proteins, the ability to actually absorb water. And that's exactly what gives the mucous membranes the ability to lubricate those epithelial cells. On top of that, these carbohydrates are very sticky and they can basically trap pathogenic and infectious agents. And so that means the mucints that form the mucus barriers basically have the ability to lubricate and protect epithelial tissue.
