You are investigating the structure of the seeds of a newly discovered tropical plant. There is storage material inside the seed
. You treat the seed with peptidase (an enzyme that breaks peptide bonds), glycoside hydrolases (an enzyme that breaks ββ glycosidic bonds), and amylase (an enzyme that breaks αα glycosidic bonds). Only the amylase appears to dissolve the storage material in the seed. What does this tell you about the identity of the storage material?
Since only starch have alpha glycosidic bond among all other macromolecules, and only amylase is appear to dissolve the storage material in the seed so the storage material is starch as a source of carbon and energy.
Since it is only amylase that produces a positive effect through its actions on the alpha-alpha bonds of the storage materials; the substance must be starch
Starch is made up of alpha-alpha glucose of amylose and amylopectin, not beta-beta-glucose, it is made up of alpha -glycosidic bonds not peptide or beta-glycosidic. Therefore peptidase, and glycoside hydrolases, can not have a positive effects on these storage materials because the enzymes and substrate bonds are different. Therefore enzyme-substrate complex formation will be not be possible; to dissolve the storage materials,
