Carbohydrates and fats can be broken down by strong acids or bases. Hydrolysis of starch is the process of digestion. ... Report Sheet: Experiment 5.
In the presence of amylase a sample of starch will be hydrolyzed to shorter polysaccharides
In this Laboratory the work of testing the influence of amino acids on the hydrolysis of starch by amylases has been done under much more.

Acid–Catalyzed Hydrolysis of Starch 1 Place 5 0 mL of starch solution in a 150 x 15 – mm test tube and add 1 0 mL of dilute sulfuric acid (3 M H 2 SO 4) Mix it by gently shaking the test tube Heat the solution in a boiling water bath for about 5 min 2 Using a clean medicine dropper transfer about 3 drops of the starch solution into a
phous regions during this hydrolysis 18 Acid conversion of non-crosslinked starch esters or ethers in aqueous ethanol (6 weight percent water) at 50–150°C and under pressure produced degraded cold-water-soluble starches 19 Suggested applications for the products which formed clear transparent ?lms were for wall covering and other
on hydrolysis of starch using acid and the findings are summarized in Table 3 Bej et al (2008) had investigated on concentrated acid hydrolysis (H 2 SO 4) of wheat flour in a batch reactor at different temperatures and acid concentrations A maximum conversion (42 ) of starch to the reducing sugars was obtained at 95°C and pH 3 Other than
EXPERIMENT 5-HYDROLYSIS OF STARCH BY ?-AMYLASE Starch is mainly composed of two parts: - Amylose: a linear polymer made up of ?-1-4 bound D-glucose units This polysaccharide is making up approximately 20-30 of the structure - Amylopectin: a polysaccharide with highly branced polymer of ?-1-6 bound glucose units
