		For instance, the salivary amylase (ptyalin) or starch-splitting enzyme of the mouth is active only in an alkaline media and is destroyed by a mild acid.
		The starch-splitting enzyme ptyalin in the saliva plays an important role as the food is chewed.
		Ptyalin requires a neutral or slightly alkaline medium for proper functioning and this is the normal condition of the saliva in the mouth.

	This weeks feature - Starch Digestion
		Starch digestion begins in the mouth with the action of the enzyme ptyalin, which converts starches into sugar during mastication and insalivation.
		If ptyalin is the only agent in the body capable of initiating starch digestion (and this is not certain) or whether it is simply the body's first opportunity to initiate starch digestion, we must not discard its importance.
		If the ptyalin is destroyed or its action is inhibited and the digestion of starches is interrupted, the partially digested starch proceeds to the duodenum, where further starch-splitting enzymes are secreted.

		Where the transformation of starch is achieved by ptyalin, the process stands at the boundary of that which takes place, in man, in the domain referred to in the second chapter as the organization of the ego.
		This is the case in the domain where the ptyalin influences lie.
		Starch, consumed and transformed into sugar by ptyalin or in the gastric juice, reveals the action in the mouth or in the stomach, of the astral body working with the ego-organization and submerging the latter.

		The device analyzes ptyalin, a digestive ferment in human saliva, for determining the level of stress.
		The higher ptyalin content is in the saliva, the stronger the level of stress gets.
		The way to gauge stress levels by measuring the ptyalin contents was discovered by Japanese researchers at Fukusima University back in 2002.

		For this reason, grass-and-leaf eaters have 24 special "molar" teeth and a slight side-to-side motion to grind their food, as opposed to the exclusively up-and-down motion of carnivores.
		Their skin has millions of pores for sweating, and they also have molars to grind and chew their food; their saliva is alkaline, and, like the grass-and-leaf eaters, it contains ptyalin for predigestion.
		Their intestines are extremely convoluted and are twelve times the length of their body, for the slow digestion of fruits and vegetables.

	Carbohydrates and ptyalin
		That the salivary enzyme alpha-amylase (ptyalin) is not produced by the glands in the mouth if you eat starches together with simple sugar.
		Because when the simple sugar is recognised by the taste, there is no need to add ptyalin to break starches down.
		Does it all mean, that ptyalin is maybe something we didn't have from "the Start" (as is the case with another enzyme lactase)?

	Digestion of Carbohydrates (Site not responding. Last check: 2007-09-18)
		Carbohydrate digestion is first initiated in the mouth, and it is therefore, essential that food be chewed adequately to allow this process to take its course.
		The enzyme ptyalin occurs in saliva and it converts the starch found mainly in vegetables, grains and legumes into the disaccharide maltose.
		Ptyalin is activated below pH4 so that starch digestion will cease in the stomach if the pH drops below this level.

	Food and diet... Acid and starch.
		"Any acid taken together with starch suspends secretion of ptyalin, a biochemical fact of life upon which all physicians agree.
		Therefore, if you consume oranges, lemons and other acid fruits, or acids such as vinegar's, along with starch, no ptyalin is secreted in the mouth to initiate the first stage of digestion.
		Consequently, the starch hits the stomach without the vital alkaline juices it needs to digest properly, permitting bacteria to ferment it instead.

	Digestion
		The enzyme ptyalin or amylase in the saliva begins to break down the food in the mouth.
		Food does not stay in the mouth long enough for ptyalin to complete the breakdown of starches.
		Yet the action of ptyalin continues for several hours after food has entered the stomach...until the food is mixed with the stomach secretions.

		These inflammatory reactions normally happens to organs which are in contact with the outside environment, such as your skin and lungs and would include problems such as psoriasis, eczema, hives, insect bites, allergic bee and bug stings, topic dermatitis, and all types of herpes as well as lung problems including asthma and emphysema.
		Ptyalin (that is amylase found in your saliva) begins polysaccharide digestion in the mouth and the process is completed in the small intestine by amylopsin (amylase excreted by the pancreas).
		It is also involved in digesting and getting rid of dead white blood cells (a nicer name for pus) and for this reason you might be more prone to absences if you are deficient in this enzyme.

	Re: Carbohydrates and ptyalin
		When a food prevailing in starches is mixed with a food prevailing in suagr (keeping in mind that both these food are not only "starches" and "sugar" but a complex combination of nutrients)
		The ptyalin predigest the carbohydrates and then when carbohydrates are finally digested protein are then digested as the gastric secretion chance.
		When you eat two food that have a diffetent nutrients ratio or a different metabolic reaction this adjustament of the gastric secretions becomes impossible.

	Digase rationale - digestive aid
		This enzyme is called ptyalin and consists of amylolytic enzymes.
		As the food travels down the esophagus via peristaltic action, ptyalin as well as any endogenous enzymes continue the digestive process started in the mouth.
		Once the food bolus has entered the stomach, it may remain in the fundus or upper region of the stomach for as long as an hour until the food is mixed with the stomach secretions.

		The saliva moistens the food so that it can be rolled by the tongue and palate into a soft bolus.
		Saliva also has an important chemical action, for by means of an enzyme called ptyalin cooked starch in the food is converted into maltose, a kind of sugar.
		When the food is sufficiently masticated, it is pushed backwards by the tongue into the pharynx where the swallowing reflex causes a series of muscular movements which propel the food into the gullet or oesophagus and thence into the stomach.

	Is Your Body Demanding Food Enzymes?
		Those who theorize that food enzymes do not digest food in the human stomach, thereby confess ignorance of the fact that physiologists have fed test meals to human subjects, along with the food enzyme, barley amylase.
		Other physiologists fed test meals and waited for the salivary enzyme, ptyalin, to work on them.
		Later, the contents of the duodenum and stomach were pumped out and it was learned that marked digestion of the food consumed occurred in both instances.

		This is because the enzyme, ptyalin, acts only in an alkaline medium; it is destroyed even by a mild acid!
		The practice of eating starches that have been disguised by sweets is also a bad way to eat carbohydrates.
		If sugar is taken into the mouth it quickly fills with saliva but no ptyalin is present which we know is essential for starch digestion.

		"If one were to take tomatoes with potatoes, the potatoes would not be properly digested because the acid of the tomato destroys the alkaline medium which is necessary for the action of ptyalin.
		Ptyalin simply cannot function in a highly acid medium, and the potatoes must wait until they reach the small intestine for further digestion.
		The physiologist A. James wrote in "Physiology of Gastric Digestion", "The highest acidities of all are reached during the digestion of food, not when the stomach is empty."

		The mundane truth is that gum disintegration is caused by carbohydrate digestion.
		Saliva contains an enzyme called ptyalin that breaks down the branched polysaccharides of the carbohydrates into oligosaccharides.
		In other words, if you hold thoroughly masticated gum in your mouth long enough without chewing it, the saliva begins digesting the gum's carbohydrate linkages.

		Proper chewing mixes the food with the saliva, signaling the brain to begin the digestive process.
		The first enzyme action begins with salivary amylase (ptyalin) which breaks down starch into less complex sugars.
		Because most people do not chew their food enough to fully process the starch and carbohydrates, digestive problems begin in the mouth.
