Answer :
Final answer:
Amylase, also known as ptyalin, is an enzyme found in saliva and pancreatic juices. It is crucial for the digestion of carbohydrates, initially breaking them down in the mouth and further in the small intestine.
Explanation:
The substance referred to, sometimes called ptyalin, found in saliva and pancreatic juices, is an enzyme known as amylase. This enzyme is secreted by both the salivary glands in the mouth and the pancreas. Its primary function is to initiate the breakdown of carbohydrates in the food we eat. In the mouth, the process begins with the action of salivary amylase which is then continued in the small intestine by pancreatic amylase. It is important for the chemical digestion of carbohydrates, turning complex carbs into simpler sugars.
Saliva is an aqueous solution of proteins and ions secreted into the mouth by the salivary glands. It contains an enzyme called salivary amylase, which initiates the breakdown of carbohydrates. Salivary amylase continues to act on carbohydrates until it is inactivated by stomach acids. Saliva also contains other components such as mucus, immunoglobulin A, and lysozyme, which contribute to the protection and lubrication of the oral cavity.
