What is Enzyme- containing fluid it the mouth?

The enzyme-containing fluid in the mouth is called saliva. It is produced by the salivary glands, which are located under the tongue and behind the lower jaw. Saliva contains a number of enzymes, including amylase, lipase, and maltase, which help to break down carbohydrates, fats, and proteins into smaller molecules that can be absorbed by the body. Saliva also contains mucin, which is a protein that helps to lubricate the mouth and protect the teeth from decay.
