Experiment 11 – Carbohydrates - Laney College

Jan 11 2012 · When a polysaccharide is hydrolyzed the products will depend on how long the mixture is allowed to react the concentration of acid or enzyme and other factors Polysaccharides are very long and have many glycosidic bonds to hydrolyze They cannot all be hydrolyzed at the same time so the product is a mixture of dextrins maltose and glucose

Experiment  – Carbohydrates

Hydrolysis is catalyzed bystrong acids and certain enzymes For example when sucrose a non-reducing sugar ishydrolyzed the reducing sugars glucose and fructose are formed Likewise when starchis hydrolyzed the reducing sugar glucose is produced Fehling’s solution contains copper(II) sulfate sodium tartrate and sodiumhydroxide

Jan 10 2012 · In this experiment we will work with the enzyme amylase This enzyme is responsible for hydrolyzing starch In the presence of amylase a sample of starch will be hydrolyzed to shorter polysaccharides dextrins maltose and glucose The extent of the hydrolysis depends on how long it is allowed to react – if the starch is hydrolyzed

What enzyme hydrolyzes starch?

In this experiment, we will work with the enzyme amylase. This enzyme is responsible for hydrolyzing starch. In the presence of amylase, a sample of starch will be hydrolyzed to shorter polysaccharides, dextrins, maltose, and glucose.

Does hydrolyzed sucrose give a positive test with Benedict's reagent?

Hydrolyzed sucrose (a mixture of D–glucose and D–fructose) will give a positive test with Benedict’s or Fehling’s reagent as well as hydrolyzed amylose (a mixture of glucose and glucose–containing oligosaccharides).

What happens when a reducing group is hydrolyzed?

In such a low concentration, the reducing group does NOT give a positive test with Benedict’s or Fehling’s reagent. On the other hand, when a nonreducing disaccharide (sucrose) or a polysaccharide such as amylose is hydrolyzed, the glycosidic linkages (acetal) are broken and reducing ends are created.

How do you test for amylase and starch in a lab?

8. Place 4 mL of 1% starch solution in each of three clean test tubes. Place 4 mL of amylase solution in 3 separate clean test tubes (so you will have a total of six test tubes: 3 containing starch and 3 containing enzyme).
