Study of digestion of starch by salivary amylase and effect of ph and temperature on it

Mix the solutions well by shaking the tube carefully and start a step watch. That is, the enzyme ptyalin or amylase present in human saliva hydrolyse the big molecules of ood into many molecules. To study the effect of temperature on the digestion of starch by saliva. Saliva mixes up with the food and helps its digestion.

Saliva mixes up with the food and helps its digestion. To study the effect of pH on the salivary digestion of starch. Mix the solutions well by shaking the tube carefully and start a step watch. Thus saliva not only helps in digestion of food but convert it into energy generating substances.

Spit this into a beaker. Add 2 ml of saliva solution into it. That is whole of the starch has got digested or hydrolysed. Finally, I am thankful to my parents for helping me economically and my friends for giving me a helping hand at every step of the project.

Effect of temperature on the digestion of starch by saliva. Add 5ml of the starch solution, 2ml of the saliva solution in each test tube. For example starch into mono-saccharides maltose and glucose; proteins into amino acids and fats into fatty acids and glycerol.

Further, enzymes and their activity are very sensitive to temperature and PH. Spit this into a beaker. Add 2 ml of saliva solution into it.

Further, enzymes and their activity are very sensitive to temperature and pH. For example, hydrolysis of starch can be verified y testing it with iodine solution. Starch forms blue coloured complex with iodine.

Note the colour produced, if any.

Conclusion Starch get hydrolysed by saliva amylase. That is whole of the starch has got digested or hydrolysed. Note the intensity of blue coloured form.

Now add 2 ml of water inn test tube No. Objectives of the Project 5.

To Study the Digestion of Starch by Salivary Amylase and Effect of pH and Temperature on it

Filter, if there is any suspended impurity clear filtrate is saliva solution and contains enzyme ptyalin. Starch forms blue coloured complex with iodine. To study the effect of pH on the salivary digestion of starch Take three test tubes and label these 1, 2, 3.

Conclusion Starch get hydrolysed by saliva amylase. Keep the three test tubes in water at room temperature for about 10 minutes.

Chemistry Experiment Procedure

Now add 2 ml of water inn test tube No. Thus saliva not only helps in digestion of food but convert it into energy generating substances. Even a slight variation in these two factors, can disrupt the action of enzymes.

Take three test tubes and label these 1, 2, 3. If no starch is present in a system it will not give blue colour with iodine.

Note the colour produced, if any. Conclusion Temperature effects the digestion of starch by saliva with increase in temp salivary analyse get inactivated and process of digestion do not take place.

To study the effect of pH on the salivary digestion of starch. For example, hydrolysis of starch can be verified by testing it with iodine solution. Introduction Every health book insists on the chewing of food.

(Signature of Student) Objectives of the Project Report 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. Aim To Study the Digestion of Starch by Salivary Amylase and Effect of pH and Temperature on it Theory Every health book insists on the chewing of food.

The act of chewing stimulates the excretion of saliva. Saliva mixes up with the food and helps its digestion. That is, the enzyme ptyalin or.

Project on chemistry: study of digestion of starch by salivary amylase Objectives of the Project Report 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.

The effect of temperature and pH on the activity of salivary amylase on starch can be studied by using the Iodine test.

If we add saliva on starch, the salivary amylase present in saliva gradually acts on starch and converts it into maltose.
