Some of these mucins can interact with other mucin molecules to create a complex network that establishes a barrier against pathogens and other invaders.
But mucus contains mucins, antimicrobial peptides, antibodies, and even bacteria-hungry viruses called bacteriophages that all work together to prevent biofilms from forming.
This saliva contains a special ingredient called mucin, which is a protein that loves to soak up water, creating a kind of gel which forms a thin, protective coating all over your mouth parts.
