When starch is hydrolysed, the glycosidic bonds are broken down

A) 1 and 4

Alpha amylase is an enzyme which helps in the digestion of starch. Its digestion begins in the mouth.

Starch is a form of complex carbohydrate i.e consisting of multiple sugar units (polysachharides). It a mixture of amylose ( [tex]\alpha -1,4[/tex]  linked glucose polymers ) and amylopectin ( [tex]\alpha -1,4[/tex] linked glucose polymers branched by [tex][/tex][tex]\alpha -1,6[/tex] linkage)

Alpha-amylase performs the digestion of starch by hydrolyzing [tex]\alpha -1,4[/tex] glucosidic bond.
