how will you test presence of carbohydrates and proteins in potatoes
Answers
Real Lab Procedure
Test for Carbohydrates
Test For Glucose
Benedict's Test
Materials Required:
Procedure:
Using a dropper, take a small quantity of Benedict’s reagent.
Add the reagent to the test tube containing banana extract.
Boil the sample over a burner for 2 minutes holding the test tube firmly with a test tube holder.
Keep shaking the test tube as it is being heated.
A brick red precipitate appears, indicating the presence of glucose in the banana extract.
Conclusion:
On boiling banana extract with the Benedict’s reagent, the cupric ion present in the Benedict’s reagent is reduced by the reducing agent, sugar, to form a brick red coloured precipitate of cuprous oxide.
Potatoes have all nine amino acids, but they don't have an adequate amount of all of them to be considered complete protein. Like most other plant food, potatoes are incomplete proteins. One large baked russet potato has 8 grams of protein.
