The enzyme used in the hydrolysis of starch to dextrin and maltose is?
lipase
amylase
invertase
zymase
설명
Starch is hydrolyzed by dilute acids to yield a mixture of dextrin (a shorter chain intermediate product), disaccharides (mainly maltose) and glucose. Further hydrolysis will eventually give glucose. Hydrolysis of starch to dextrin and maltose can also be brought about by the enzyme amylase present in saliva and in malt.
