Guida verificata passo dopo passo1
Identify the role of amylase in human digestion, which is to catalyze the hydrolysis of specific carbohydrates.
Recall that amylase specifically targets polysaccharides composed of glucose units linked by alpha-glycosidic bonds.
Recognize that starch, which includes amylose and amylopectin, is a polysaccharide made of glucose units connected by alpha-1,4 and alpha-1,6 glycosidic bonds, making it a substrate for amylase.
Understand that cellulose is a polysaccharide with beta-1,4 glycosidic bonds, which human amylase cannot break down due to the different bond type.
Note that triacylglycerols are lipids, not carbohydrates, and lactose is a disaccharide broken down by lactase, not amylase.
