Homework Answers
Ans) Whenever starch (polysaccharides) molecules undergo hydrolysis, it forms either monosaccharides, disaccharides or trisaccharides. The end products depends on the strength of enzymes used and the common enzymes are, α-Amylase, which produces the disaccharide maltose and the trisaccharide maltotriose.
- Enzymes involved in the processing of starch to sugars. The commercial processing of starch to mono- and oligosaccharides depends on the availability of three major enzymes — glucoamylase, alpha-amylase and glucose isomerase.
- Use of starch is accomplished by an enzyme called alpha-amylase. A medium containing starch is used. After inoculation and overnight incubation, iodine reagent is added to detect the presence of starch. Iodine reagent complexes with starch to form a blue-black color in the culture medium.
