Saliva is a watery substance formed in the mouths of animals, secreted by the salivary glands. Human saliva comprises 98% water, plus electrolytes, mucus, white blood cells, epithelial cells, glycoproteins, enzymes, antimicrobial agents such as secretory IgA and lysozyme. The enzymes found in saliva are essential in beginning the process of digestion of dietary starches and fats. These enzymes also play a role in breaking down food particles entrapped within dental crevices, thus protecting teet
2) Bacteria in the vagina - These bacteria tended to be breaking down more simple sugars, and also had carbohydrate forming enzymes in order to build up biofilms 3) Bacteria in the mouth - these bacteria have a wide range of carbohydrate digesting enzymes in order to break down the bits of food which get trapped in your teeth. The researchers also identified three enzymes used for metabolising dextran, which may be unique for mouth-bacteria and seemed to be a marker for plaque formation.
