Ptyalin (Salivary amylase) is a CHO splitting enzyme. It acts on only boiled starch. It helps digestion by breaking down starches and glycogens as they enter our mouth. It cannot act on unboiled starch because it cannot penetrate the protective membrane of unboiled starch. After starches leave the mouth and enter the stomach, the ptyalin is destroyed by stomach acids. It is an enzyme that is a division of our saliva and aids with digestion. Enzymes are compounds that aid speeds up chemical reactions.

Boiled starch → (Ptyalin) → Ervthrodextrin → (Ptyalin) → Acrodextrin → (Ptyalin) → Maltose.

Following are the steps in the procedure of digestion of carbohydrate in buccal cavity, showing the action of Ptyalin:

  • Boiled starch + Ptyalin = Soluble starch
  • Soluble starch + Ptyalin = Erythrodextrin + Maltose
  • Erythrodextrin + Maltose + Ptyalin = Acrodextrin + Maltose
  • Acrodextrin + Maltose + Ptyalin = Isomaltose + Maltose

In the case of saliva, the enzymes help speed up reactions that break down the food we eat. Even before food makes it to your stomach it begins to break down, and enzymes help make the procedure go easily. Starches come in a number of dissimilar forms and are eaten on a daily source by most humans. Bread, rice, pasta, potatoes, corn, and wheat are all dissimilar forms of starches. Starches are vital to humans because they provide a huge amount of their energy needs.
