Yes they do. It's used to digest carbohydrates.
Amylase is the enzyme made in the salivary glands and the pancreas. Its function is to break down complex carbohydrates, sometimes called starches.. In the mouth they are called salivary amylase and in the small intestine they are called pancreatic amylase. This enzyme is also known as ptyalin.
Because the enzyme salivary amylase lacks protein.
The enzyme amylase (for breaking down starch) is produced by the salivary glands along with water and mucus
Saliva
Digestion of starch and other carbohydrates begins in the mouth with an enzyme called salivary amylase.
salivary amylase.
4) lack protein
There are three major enzymes in saliva. These enzymes are amylase, Lingual lipase, and Kallikrein. There are four antimicrobial enzymes that help kill bacteria, including lysozyme, salivary lactoperoxide, lactoferrin, and immunoglobulin A.
The oral cavity has limited digestion of carbohydrates and lipids (amylase and lipase).The tongue is involved in secretion of mucins and the enzyme lingual lipase (breaks down some fats).The parotid salivary glands produce a serous secretion containing large amounts of salivary amylase (carbohydrates).The submandibular salivary glands secrete a mixture of buffers, glycoproteins called mucins, and salivary amylase.
The small intestine and the salivary glands are the organs of the digestive system that produces the enzyme amylase.

http://www.answers.com/topic/salivary-glandAmylase in the saliva is known as Ptyalin.Humans have this enzyme in their saliva, but some mammals, like horses, dogs, and cats, do not.Ptyalin begins carbohydrate and polysaccharide digestion in the mouth; the process is completed in the small intestine by the pancreatic amylase, sometimes called amylopsin.dextrin
