Saliva contains the enzyme salivary amylase.
Salivary Amylase: The Enzyme in Saliva
Salivary amylase is the key enzyme present in saliva. It plays a vital role in the initial stages of digestion. According to the provided reference, salivary amylase is a glucose-polymer cleavage enzyme produced by the salivary glands. This means it starts breaking down starches (glucose polymers) into simpler sugars right in your mouth.
Function of Salivary Amylase
- Breaks down starches: Salivary amylase initiates the digestion of carbohydrates by hydrolyzing starch into smaller molecules like dextrins and maltose.
- Produced by Salivary Glands: Specifically, the salivary glands are responsible for the production and secretion of this crucial enzyme.
- Begins Digestion in the Mouth: This enzyme allows digestion to start early. This is beneficial because the more time food has to break down, the more efficiently the body can process nutrients.
In summary, salivary amylase is a critical component of saliva that begins the chemical digestion of carbohydrates.
