Saliva on a baby's lips. Saliva (commonly referred to as spit or drool) is an extracellular fluid produced and secreted by salivary glands in the mouth.In humans, saliva is around 99% water, plus electrolytes, mucus, white blood cells, epithelial cells (from which DNA can be extracted), enzymes (such as lipase and amylase), and antimicrobial agents (such as secretory IgA, and lysozymes).
Digestion: Saliva contains amylase, which hydrolyses starch into glucose, maltose, and dextrin. As a result, saliva allows some digestion to occur before the food reaches the stomach. [30] Taste: [31] Saliva acts as a solvent in which solid particles can dissolve and enter the taste buds through oral mucosa located on the tongue. These taste ...
Amylase may be measured in other body fluids, including urine and peritoneal fluid. A January 2007 study from Washington University in St. Louis suggests that saliva tests of the enzyme could be used to indicate sleep deficits, as the enzyme increases its activity in correlation with the length of time a subject has been deprived of sleep.

Your body naturally spends more time in deep sleep, the stage of sleep that conserves energy, so your immune system can focus on fighting infection. Adults should aim for at least seven hours of ...
Finally, the caramelization process in soda production can form harmful compounds called advanced glycation end products (AGEs), which may play a role in cancer development. Igor-Kardasov ...
Mastication of the food with the help of saliva and mucus results in the formation of a soft bolus which can then be swallowed to make its way down the upper gastrointestinal tract to the stomach. [19] The digestive enzymes in saliva also help in keeping the teeth clean by breaking down any lodged food particles. [20] [15]

The first step in the production of high-fructose corn syrup is the treatment of cornstarch with α-amylase, which cleaves the long starch polymers into shorter chains of oligosaccharides. An α-amylase called "Termamyl", sourced from Bacillus licheniformis , is also used in some detergents, especially dishwashing and starch-removing detergents.
