Effect of different temperatures on the activity of salivary amylase on starch materials required three series of test tubes having iodine solution in each, test tubes, ice cubes, water, 15 ml 1% starch solution + 3 ml 1% nacl, saliva solution, droppers, thermometer, bunsen burner and wire gauze. Amylase is a digestive enzyme that acts on starch in food, breaking it down into smaller carbohydrate molecules the enzyme is made in two places first, salivary glands in your mouth make salivary amylase, which begins the digestive process by breaking down starch when you chew your food, converting it into maltose, a smaller carbohydrate. Ex 39b chemical & physical processes of digestion: be sure to read the intro in the lab activity 1 assessing animal starch digestion by salivary amylase. Amylase and lipase are key digestive enzymes amylase helps your body break down starches lipase helps your body digest fats the pancreas is a glandular organ that sits behind the stomach and.

1) digestion is the break down of large complex and insoluble food into small simple soluble molecules for the body to absorb it starch is a complex, the body have to find a way to break down starch, so the body produces salivary amylase in the mouth to begin the break down of starch into maltose amylase works in the ph of alkaline. In the current study, we determined whether increased digestion of starch by high salivary amylase concentrations predicted postprandial blood glucose following starch ingestion. Amylase is an enzyme present in human saliva used to hydrolysis starch into maltose it aids in the speed up of digestion it aids in the speed up of digestion objective the objective of this lab was to test the presence of starch and reducing sugar within a solution of starch and amylase. Salivary amylase is calculated as the difference between the total and pancreatic amylase. This video goes through the steps of a laboratory investigation that shows how starch, a complex carbohydrate, is broken apart into simple sugars.

An enzyme produced by either the panceas or the salivary glands that aid is the digestion of food, sugars. Name: _____ date: _____ lab # 16 b digestion of starch by amylase introduction saliva is a watery fluid produced by salivary glands that open into your mouth. Enzymatic activity of salivary amylase abstract: salivary amylase is an enzyme that can digest starch molecules and break them down to sugar molecules in this experiment, the enzymatic activity and specificity of salivary amylase was examined depending on the changes in ph and temperature.

1 digestion lab experiment #1: carbohydrate digestion • tube 1 - 3 ml water • tube 2 - 3 ml 02% amylase • tube 3 - 3 ml 02% amylase + 10 drops of. The main objective of this chemistry project report is to study the digestion of starch by salivary amylase and effect of temperature and ph on it and to study digestion of starch by saliva to study the effect of temperature on the digestion of starch by saliva. Salivary amylase is good for showing the effects of temperature and ph on enzyme activity as it is relatively sensitive to both conditions, though the optimum temperature is considerably higher than is usually given in school textbooks. Salivary amylase initiates carbohydrate digestion (39) human pancreatic juice amylase has no sugar groups and exists as laboratory levels greater than three.
