The saliva helps make the cracker moist and is easier to break down.
On foods like crackers which are dry, salivary amylase helps moisten the food so it is easier to chew and swallow and to prevent scratching the throat.
About 7.4 pH.
Amylase is produced by the salivary glands and works in the mouth to break down chardohydrates(digests starch into maltose). It only works for a short amount of time because when you swallow the food it is inhibated by the acid in the stomach. Amylase works best at a pH of 7.
In the mouth, salivary amylase works to break down cooked starch into maltose. The duodenum (first part of the small intestine), pancreatic amylase works to do the same. Amylase only works in these places because they provide the optimum pH conditions for amylase to work (range from pH 6 - 8).
Both. Salivary amylase works in your mouth, and the others in your stomach and duodenum.
Pancreatic amylase is primarily produced in the pancreas, specifically in the acinar cells. It is then released into the small intestine where it helps in the digestion of carbohydrates by breaking down starches into simple sugars like maltose and glucose.
Salivary amylase functions best in a neutral to slightly acidic environment, with an optimal pH range between 6.7 to 7.4. This enzyme works to break down starches into simpler sugars in the mouth before the food reaches the stomach.
Amylase is not active in the stomach, the environment is too acidic. This is why the pancrease produces and secretes amylase into the duodenum after food leaves the stomach, to replace the amylase secreted by salivary glands and denatured by stomach acid.
Saliva digests carbohydrate. Saliva contains a carbohydrase enzyme called amylase, which breaks down carbohydrates. Amylase is also produced later on in the digestive system and so the amylase here is immaginatively termed salivary amylase.Saliva contains the enzyme amylase (here it is called called salivary amylase) which is responsible for part of the digestion of carbohydrates like starch.
HCl activates pepsinogen to form pepsin, which is the active form of the enzyme pepsin necessary for protein digestion in the stomach. However, HCl does not directly affect salivary amylase. Salivary amylase works optimally at a neutral pH in the mouth before food reaches the stomach, where it begins the digestion of starch into smaller sugars before being inactivated by stomach acid.
Salivary amylase. This enzyme helps to turn starch into a sugar called maltose...when your food gets into the small intestine, more amylase is made by the pancreas also.Another enzyme called maltase, turns all this maltose into glucose. Glucose is then absorbed into the blood.
Salivary amylase works well around pH 7 (inside the mouth), but inside the stomach are gastric juices which contain HCl. Since the HCl drops the pH of the solution significantly, it denatures the amylase so that it will no longer function as it normally would, breaking down starch and glycogen.
