Starch Hydrolyzing Enzymes: Alpha-Amylase

Starch hydrolyzing enzyme is the second most important commercially available enzyme, accounting for 30% of the world's enzyme consumption, accounting for 25% of the world's enzyme market share. Among them, α-amylase is the most important starch hydrolyzing enzyme and is used in many applications in starch processing, breadmaking, automatic dishwashing detergent, fiber desizing, medicine, pulp and paper, and brewing industry . However, the requirements of each industry are very specific and are mainly related to pH, oxidative stability, chelating agent tolerance and temperature behavior.

Amylase is an enzyme that hydrolyzes starch and breaks down starch into its constituents. When the starch is completely hydrolyzed, glucose becomes the final product. A starch solution was prepared by adding 1 gram of cornstarch to 10 ml of distilled water; the mixture was poured into 50 ml of boiling water and stirred until the solution became clear. You can get amylase from your own saliva. Collect 1-2 ml of saliva in a test tube and add 50 ml of water. 4 ml of the starch solution was placed in 3 tubes and 4 ml of amylase solution was placed in 3 tubes. The starch and amylase tubes were placed in each water bath for 10 minutes, placed in a cold bath using 5 ° C., room temperature bath using 37 ° C., and a thermal bath using 100 ° C. Amylase was poured into the starch and the tube was returned to each bath for 10 minutes. Four drops of each mixture are placed in separate spot plates and 1 drop of iodine is added to each sample

Alpha amylase is an enzyme. It binds specifically to water and starch. It hydrolyzes starch and glycogen to produce glucose and maltose. It acts on alpha binding of polysaccharides. Due to the specificity of the enzyme activity, the structure of the enzyme must be accurate. Any factor that causes enzymatic denaturation will limit its activity. The two most important factors that influence alpha amylase activity are temperature and pH. The following experiment was conducted to investigate the effect of different ambient temperature and pH on the activity of barley amylase.

Enzymes are proteins found in all living cells.
